(Remember, PEMDAS)
First find what 5^2 equal to
5 • 5 = 25
Then add 25 to 3
25 + 3 = 28
So Oc. :)
Answer: The answer would be c
Step-by-step explanation:
Step 1: Solve for b
5a+b=7
b=-5a+7
your slope would be -5a
Step 2: Make it perpendicular
The Perpendicular is gonna be the opposite
So it would be b= 1/5+7
The slopes has to be different and you don't have to worry about the "+7"

Answer:

Step-by-step explanation:
The composite figure consists of a square prism and a trapezoidal prism. By adding the volume of each, we obtain the volume of the composite figure.
The volume of the square prism is given by
, where
is the base length and
is the height. Substituting given values, we have: 
The volume of a trapezoidal prism is given by
, where
and
are bases of the trapezoid,
is the length of the height of the trapezoid and
is the height. This may look very confusing, but to break it down, we're finding the area of the trapezoid (base) and multiplying it by the height. The area of a trapezoid is given by the average of the bases (
) multiplied by the trapezoid's height (
).
Substituting given values, we get:

Therefore, the total volume of the composite figure is
(ah, perfect)
Alternatively, we can break the figure into a larger square prism and a triangular prism to verify the same answer:
