Answer: 5a + 5b + 5 - x(a + b)
Step-by-step explanation:
(a + b + 1)2 – (a + b + 1)(x - 2) + (a + b + 1)
2a + 2b + 2 - (ax - 2a + bx -2b -2) + (a + b + 1)
2a + 2b + 2 - ax + 2a - bx +2b +2 + a + b + 1
5a + 5b + 5 - x(a + b)

Answer:
B. [tex]9(\frac{4}{5} * \frac{1}{3})[/tex]
Step-by-step explanation:
In mathematics, the associative property is a property of some binary operations, which means that rearranging the parentheses in an expression will not change the result. In propositional logic, associativity is a valid rule of replacement for expressions in logical proofs.
As the associate property is switching the numbers in the parentheses, B is the answer as it switched the [tex]\frac{1}{3} and \frac{4}{5}[/tex] while keeping the equation the same, and not editing any information that would change the outcome (answer) of the problem.

Step-by-step explanation:
x = price of pants
y = price of top
x + y = 36
x = (4/5)y
we use the second equation as substitute in the first
(4/5)y + y = 36
4y + 5y = 180
9y = 180
y = $20
x = (4/5)y = (4/5)×20 = 4×4 = $16

Noah has a box of coins in his room. The box currently
contains 40 coins, consisting of pennies, dimes, and
quarters. The number of pennies is equal to the
number of dimes, and the total value of the coins is
$8.05. How many of each type of coin does Noah have
in the box?
The currency called the dollar can be divided or reduced into smaller forms also known as pennies, quarters, nickels and dimes.
The number of pennies is 5, the number of dimes is 5, the number of quarters is 30.
It is important to note that
a penny = $0.01
a dime = $0.10
a quarter = $0.25
Let's represent the number of
pennies = p
dimes = d
quarters = q
The number of pennies is equal to the number of dimes, hence:
p = q, so we can represent the number of pennies and dimes as y
The box currently contains 40 coins
So: 40 = y + y + q
q = 40 - 2y...........Equation 1
The total value of the coins is $8.05
So: 0.01y + 0.1y + 0.25q = 8.05 ........... Equation 2
We substitute 40 - 2y for q in Equation 2
0.01y + 0.1y + 0.25(40 - 2y) = 8.05
0.01y + 0.1y + 10 - 0.5y = 8.05
Collect like terms
0.01y + 0.1y - 0.5y = 8.05 - 10
-0.39y = -1.95
Divide both sides by -0.39
-0.39y/-0.39 = -1.95/0.39
y = 5
Since y represents the number of pennies and dimes, the number of pennies is 5 and the number of quarters is 5.
To solve for the number quarters, we would use equation 1
q = 40 - 2y...........Equation 1
q = 40 - 2 x 5
q = 40 - 10
q = 30
The number of quarters is 30.
Therefore, we have 5 pennies, 5 dimes, and 30 quarters.

Answer:
[tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth
Step-by-step explanation:
1. Find the area of the base and the top, which are circles.
Area of circle : [tex]\pi 10^{2}[/tex] = 986.960440109
There are 2 circles, soooooo....= 986.960440109 x 2 = 1973.92088022
2. Find the rest of the area of the cylander.
So, we have to find the circumference of the circle.
Circumference :2[tex]\pi[/tex]10 = 62.83
3. Multiply circumference by height.
62.83 x 7 = 439.81
4. Add all of the products.
439.81 + 1973.92088022 = [tex]2036.75088022^{2}[/tex] or [tex]2036.8^{2}[/tex] rounded to the nearest tenth

The surface area in square meters of the human body can be found using the expression √hm/3600 where h is the height in centimeters and m is the mass in kilograms. find the surface area of a 15-year-old boy with a height of 183 centimeters and a mass of 74 kilograms. (√ = square root)
The surface area is a function of height and mass of the body
The surface area of the 15-year-old boy is 1.92 cm square
The given parameter is:
[tex]A = \sqrt\frac{{hm}}{3600}[/tex]
When h = 183 cm ad m = 74 kg
The function becomes
[tex]A = \sqrt{\frac{180 \times 74}{3600}[/tex]
[tex]A = \sqrt{\frac{13320}{3600}[/tex]
[tex]A = \sqrt{3.7}[/tex]
[tex]A = 1.92[/tex]
Hence, the surface area of the 15-year-old boy is 1.92 cm square
