What is the surface area of the prism?A. 82 yd.^2
B. 90 yd.^2
C. 96 yd.^2
D. 108 yd. ^2

Answers

Surface area of the prism= surface area of the base + surface area of the two triangles + surface area of the two rectangles.

Surface area of the base=(3 yd * 7 yd)=21 yd².
Surface area of the two triangles=2*(3 yd * 4 yd)/2=12 yd².
Surface area of the two rectangles=(7 yd * 5 yd) + (7 yd * 4yd)=35 yd² + 28 yd²=
=63 yd²

Surface of the prism=21 yd² + 12 yd² + 63 yd²=96 yd²

Remember:
surface area of a triangle=(base * height)/2
surface area of a rectangle=base * height.

Answer: C.96 yd²

Answer:

C.96 yd²

Rhea is solving a math puzzle. To find the solution of the puzzle, she must find the product of two numbers. The first number is the sum of 23 and x, and the second number is 18 less than two times the first number. Which of the following functions represents the product of these two numbers?Opions are:

A.
P(x) = 2x^2 + 74x + 644
B.
P(x) = 2x^2 + 28x - 414
C.
P(x) = 2x^2 + 102x + 1,288
D.
P(x) = 2x^2 + 110x + 1,472

Answers

Answer:

It's B.

Step-by-step explanation:

First is x + 23 and second is 2x - 18.

So the product is

(x + 23)(2x - 18)

= 2x^2 - 18x + 46x - 414

= 2x^2 + 28x - 414
