Answer:
A. 2564 cm^2
Step-by-step explanation:
There are two triangles (Which both are the same) and three different rectangles.
1. Let's solve the area of the triangles first!
Formula: bh(1/2)
10(26)(1/2)
130
2. Now, let's multiply by 2 since there's two of them:
130(2) = 260
3. So, we got 260. Let's find the area of the three rectangles!
Formula: bh
Rectangle A: 28(36) = 1008
Rectangle B: 10(36) = 360
Rectangle C: 26(36) = 936
4. Add the area of the triangles and the rectangles!
260 + 1008 + 360 + 936 = 2564
So the surface area is 2564 cm^2

I believe your answer is C. But I’m not completely sure!
Answer:
1) D. 
2) E. The coefficient of 
is -16.
Step-by-step explanation:
1) A polynomial is an algebraic expression of the form 
, where 
is the grade of the polynomial. In this case, the only equation that satisfies this definition is:
Correct answer: D
2) Let 
, we proceed to expand the expression by algebraic means:
We see that coefficients for 
and are -16 and 0, respectively. Hence, the incorrect answer is E.
