[tex]1[/tex]Box - 2 :
[tex]x = 1[/tex]Perform the indicated operation.
Answer:
[tex]4 {x}^{3} + 2 {x}^{2} - 8x - 4[/tex]
Step-by-step explanation:
it's simple, just multiply
f.g(x)=(x^2-2)(4x+2)=4x^3+2x^2-8x-4
Step-by-step explanation:
Hi there!
f(x) = x²-2
g(x) = 4x+2
Then;
f(x).g(x) = (x²-2)*(4x+2)
= x²(4x+2) -2 (4x+2)
= 4x³ + 2x² - 8x - 4
Therefore, the answer is f(x).g(x)= 4x³ + 2x² - 8x - 4.

87 calories per 3/4 cup. How many calories per 1 cup
since 87 calories = ³/₄ cup
let x calories = 1 cup
⇒ 87 = ³/₄ x
x = (87)(⁴/₃)
x = 116 calories
∴ if 87 calories is in 3/4 cup, then 1 cup contains 116 calories.helpppppppppp me plsssssssssssssssss

The measure of the third angle in an isosceles triangle is 55.5 more than the measure of either of the two equal angles. Find the measure of the third angle
Answer:
The third angle is 97º
Step-by-step explanation:
a triangle has 180º total
so 180-55.5=124.5
124.5÷3=41.5
then add the 55.5 back
41.5+55.5=97
97º
Write the equation of the line that passes through the given point and is perpendicular to the given line
please explain if you can, but if you dont want to its okay
Answer:
y = 5Step-by-step explanation:
The line x = 3 is parallel to y- axis, the perpendicular line is going to be parallel to x- axis and will have an equation:
y = aSince it passes through the point (-2, 5), it will have a = 5:
y = 5 is the line we needWhich expression identifies the multiplicative identity property
Answer:
Step-by-step explanation:
5x(1)=5x
Answer:
The answer is A
Step-by-step explanation:
The multiplicative identity property is applied to numbers in the operation of multiplication. The property states that when a number is multiplied by the number 1 (one), the product will be the number itself. This property is applied when numbers are multiplied by 1. Here, 1 is known as the multiplicative identity element because when we multiply any number with 1, the obtained result will be the same number. This property can be applied to real numbers, complex numbers, integers, rational numbers, and so on. The multiplicative identity property is expressed as: a × 1 = a, where 'a' is any real number.
Example:
44 × 1 = 44, where 44 is the number on which we applied the multiplicative identity.
Note: The multiplicative identity is not applied when any number is multiplied by -1 because the result will not be the same number.
For example, 23 × -1 = -23
Find the exact value of each variable that represents its side length in a right triangle. Please help me with this ASAP!
Answer:
[tex]h=6[/tex]
[tex]k=2.5[/tex]
[tex]m=\sqrt{21}[/tex]
[tex]n=3\sqrt{10}[/tex]
[tex]p=\sqrt{17}[/tex]
Step-by-step explanation:
We can use the Pythagorean Theorem in each case.
Pythagorean Theorem:
[tex]a^{2} +b^{2} =c^{2}[/tex]
Where [tex]a[/tex] and [tex]b[/tex] are two sides of a right-angle triangle and [tex]c[/tex] is Hypotenuse (the longest side opposite to the right angle)
For [tex]h[/tex]:
[tex]h^{2} +8^{2} =10^{2}[/tex]
[tex]h^{2} +64=100[/tex]
Subtract 64 from both sides:
[tex]h^{2} =100-64[/tex]
[tex]h^{2} =36\\[/tex]
[tex]h=\sqrt{36}[/tex]
[tex]h=6[/tex]
We follow the same process to find [tex]k,m,n[/tex] and [tex]p[/tex].
Jenny & Natasha are working on a problem together: Solve x/3 + 8 = −2. Natasha thinks the first step is to multiply by 3. Jenny explains that this is not the most efficient way to solve. Explain who is correct & justify your reasoning.
The individual that is correct is Natasha. This is because the answer can be gotten using Natasha's method
The given equation is [tex]\frac{x}{3} + 8 = -2[/tex]
Solving the equation using Natasha's method
the fist step is to multiply by 2
x + 24 = - 6
The second step is to combine and add similar terms
x = -24 - 6
x = -30
Second method of solving the equation
The equation the friends are trying to solve is [tex]\frac{x}{3} + 8 = -2[/tex]
The first step is to combine similar terms
[tex]\frac{x}{3}[/tex] = - 8 - 2
The second step is to add similar terms together
[tex]\frac{x}{3}[/tex] = - 10
The third step is to multiply both sides of the equation by 3
x = (-10 x 3)
x = -30

Dr.Mann mixed 10.384 g of chemical A, 12.061 of chemical B, and 7.505 g of chemical C to make 5 doses of medicine. How many grams are in one dose of medicine?
Answer:
5.99g in one dose.
Step-by-step explanation:
Add up all the chemicals in the mix and divide by 5 to get how many grams are in one dose of medicine. We divide by 5 cause we get 5 doses out of the entire mixture.
[tex]\frac{10.384+12.061+7.505}{5} =\frac{29.95}{5}=5.99g[/tex]

solve 2(n + 5) = 15
solve a + a + a + a = 24
solve 4c + 6 = 18
please answer with an explanation
50 points given with explanation
Step-by-step explanation:
♤ 3(b-5) = 27
=> 3b - 15 = 27
=> 3b = 27 + 15 = 42
=> b = 42/3
=> b = 14 (Ans)
♤ 2x/3 = 6
=> 2x = 6 × 3 = 18
=> x = 18/2
=> x = 9 (Ans)
♤ 2(n + 5) = 15
=> 2n + 10 = 15
=> 2n = 15 - 10 = 5
=> n = 5/2
=> n = 2.5 (Ans)
♤ a + a + a + a = 24
=> 4a = 24
=> a = 24/4
=> a = 6 (Ans)
♤ 4c + 6 = 18
=> 4c = 18 - 6 = 12

{2x + 3y = 10 -6x + y = 20 si se resuelve por el metodo de igualación ¿ cual es la igualdad que resulta si se despeja la variable y de ambas ecuaciones?
Answer:
Step-by-step explanation:
So im gonna be using the substitution method because its easier
We divide the equations into two and solve for y
-6x+y=20
We add 6x to both sides
-6x+y+6x=20+6x
y=6x+20
Now we plug in 6x+20 for y into the other equation
2x+3y=10
2x+3(6x+20)=10 We can simplify now
20x+60=10
20x=-50
take 20 from both sides so its gonna be a fraction
-5/2
We plug in -5/2 for x
y=6(-5/2)+20
y=5
]so therefore x is -5/2 and y is 5

The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20.
What is the equation?There are many different ways to define an equation. The definition of an equation in algebra is a mathematical statement that demonstrates the equality of 2 mathematical expressions.
More than one variable may be present inside a linear equation. An equation is said to be linear if the maximum power of the variable is consistently unity.
A formula known as an equation uses the same sign to denote the equality of two expressions.
In another word, the equation must be constrained with some constraints.
Given the expression,
2x + 3y = 10 -6x + y = 20
So,
2x + 3y = 20 and 10 - 6x + y = 20
To remove y we need to find y and substitute.
So by substituting,
10 - 6(20 - 3y)/2 + y = 20
y = 7
So,
2x + 21 = 10 - 6x + 7 = 20
Hence "The equality of the expression after removing y by substituting y is 2x + 21 = 10 - 6x + 7 = 20".

3x²-x+1 is a factor of ax⁴+bx³+12x² - 6x + 1 . Then a-b equals
Answer:
a-b = 31 (a ≠ b)
Step-by-step explanation:
(3x²-x+1)(px²+qx+1) = ax⁴+bx³+12x² - 6x + 1
3px⁴+(3q-p)x³+(3+p-q)x²+(q-1)x+1 = ax⁴+bx³+12x² - 6x + 1
q-1 = -6 q = -5
3+p-q = 3+p-(-5) = 8+p = 12 p = 4
b = 3q-p = 3*(-5) - 4 = -19
a = 3p = 3*4 = 12
a-b = 12 - (-19) = 31
