Answer:
5 or -8
Step-by-step explanation:
[tex](3 \times x) + x {}^{2} = 40[/tex]
[tex]3x + {x}^{2} = 40[/tex]
[tex] {x}^{2} + 3x - 40 = 0[/tex]
using factorization method
[tex]( {x}^{2} + 8x) ( - 5x - 40) = 0[/tex]
[tex]x(x + 8) - 5(x + 8) = 0[/tex]
[tex](x - 5)(x + 8) = 0[/tex]
[tex]x - 5 = 0[/tex]
or
[tex]x + 8 = 0[/tex]
[tex]x = 5[/tex]
or
[tex]x = - 8[/tex]

Hey there!
(-12) - (+3 - 4 - 10) + (-15)
= -12 - (3 - 4 - 10) - 15
= -12 - (-1 - 10) - 15
= -12 - (-11) - 15
= -12 + 11 - 15
= -1 - 15
= -16
Therefore, your answer should be: -16

Step-by-step explanation:
Simplify the expression (4-5i)(2+6i)-(3-2i) show your work.
The simplification of the given expression [tex](4-5i)(2+6i)-(3-2i)[/tex], we get [tex]-30i^2+16i+5[/tex].
Given expression is:
[tex](4-5i)(2+6i)-(3-2i)[/tex]By applying the multiplication, we get
→ [tex](8-10i+24i-30i^2)-(3-2i)[/tex]
By multiplying the (-) sign into the bracket, we get
→ [tex]8-10i+24i-30i^2-3+2i[/tex]
→ [tex]5+16i-30i^2[/tex]
By arranging the terms, we get
→ [tex]-30i^2+16i+5[/tex]

Write this polynomial in descending order. Enter exponents using the caret
(). For example, enter x2 as x^2.
-7 + 8x2 - 4x
Answer: 8x^2 -4x -7
Step-by-step explanation: the x^2 term comes first, followed by the x, then the constant which in this case is -7
so it would be 8x^2 -4x -7
The polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.
To write the polynomial -7 + 8x² - 4x in descending order, we arrange the terms from highest degree to lowest degree.
Here's how to do it step by step:
Step 1: Identify the degree of each term:
The term -7 has a degree of 0 (since it is a constant).
The term 8x² has a degree of 2 (since it has a variable raised to the power of 2).
The term -4x has a degree of 1 (since it has a variable raised to the power of 1).
Step 2: Arrange the terms in descending order based on their degrees:
Start with the term with the highest degree and proceed in decreasing order. In this case, we have only three terms, so we start with the highest degree term:
8x² (degree 2)
Next, we consider the next highest degree term:
-4x (degree 1)
Finally, we have the constant term:
-7 (degree 0)
Step 3: Write the polynomial in descending order:
Putting the terms together in descending order, we have:
8x² - 4x - 7
So, the polynomial -7 + 8x² - 4x written in descending order is 8x² - 4x - 7.

In Earth's southern hemisphere, the summer season is from December to March and winter is from June to September. The table shows the highest temperatures recorded at the South Pole for three different months.
Graph model:
South Pole Temperatures
Month Highest temperature (°F)
January 6
June –24
November –2
Each month's highest recorded temperature is plotted on the number line.
4. Which month had the coldest of the three temperatures? Explain.
#4
June is the most coldest.
How?
Mention the temperatures
January=+6°F
June=-24°F
November=-2°F
Lowest is the coldest .(June is the coldest month)
January = 6°F
June = -24°F
November = -2°F
By the above given observation we can say that June is the coldest as it has the lowest temperature in all.
Sam walked x miles at 4mph.
Then he walked 2x miles at 3mph.
A) find average speed for the whole journey.
The second part of journey took 25mins longer than the first part.
B) Find the value of x.
Answer:
Sam average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
Step-by-step explanation:
Formula: Speed = [tex]\frac{Distance}{Time}[/tex]
i.e. Time = [tex]\frac{Distance}{Speed}[/tex]
If Sam walked x miles at 4 mph, then time taken by him = [tex]\frac{x}{4}[/tex] hours
If he then walked 2x miles at 3 mph, then time for this period = [tex]\frac{2x}{3}[/tex]hours
Average speed = [tex]\frac{Total Distance}{Total Time}[/tex]
=[tex]\frac{x+2x}{\frac{x}{4} \frac{2x}{3} }[/tex]
=[tex]\frac{3x}{\frac{x1}{4} \frac{2}{3} }[/tex]
=[tex]\frac{3}{\frac{3+8}{12} }[/tex]
=[tex]\frac{3 x 12}{11}[/tex]
=[tex]\frac{36}{11}[/tex]
=[tex]3\frac{3}{11} mph[/tex]
Hence, Same's average speed for the whole journey = [tex]3\frac{3}{11} mph[/tex]
