3(x^2 +2xh + h^2) -4(x + h) -5
(3x^2 + 6xh + 3h^2 -4x -4h -5 - ( 3x^2 -4x -5))/h
(6xh + 3h^2 -4h)/h
h(6x +3h - 4)/h
6x + 3h -4
<span>So we want to know what the area of a circular bread is if we know the diameter d=11 inches. First the diameter is equal to 2 radii, d=2r, so our radius r=11/2=5.5 inches. Now we can calculate the area. Formula for the area is A=pi*r^2. After we input our numbers we get the area A=94.985inches^2. Rounding the answer to the nearest hundreth: A=94.98 inches ^2</span>
Answer:
Option number B
Step-by-step explanation:
As per the statement:
Pieter wrote and solved an equation that models the number of hours it takes to dig a well to a level of 72 feet below sea level.
Given the equation as:
7h - 5 ( 3h -8 ) = -72
Using distributive property,
a ⋅ ( b + c ) = a ⋅ b + a ⋅ c
7h - 15h + 40 = - 72
Combine like terms;
-8h + 40 = -72
Subtract 40 from both sides we have;
-8h 8= -112
Divide both sides by -8 we have;
h = 14 hours
Therefore, the statement is true about Pieter’s solution is, It must be a positive number since it represents a number of hours.
