Find the surface area of<br> the prism.

Anton [14]

Answer:

$\text{D. }464\:\mathrm{ft^2}$

Step-by-step explanation:

The surface area of the prism consists of four rectangles and two trapezoids. The sum of the areas of these polygons will give the total surface area of the prism:

Rectangle 1 (top base): $12\cdot 14=168$

Rectangle 2 (bottom base): $6\cdot 14 = 84$

Trapezoids 1 and 2 (lateral): $2\cdot 9 \cdot 4=72$

Rectangles 3 and 4 (lateral): $2\cdot 14\cdot 5=140$

Thus the total surface area is equal to

$168+84+72+140=\boxed{\text{D. }464\:\mathrm{ft^2}}$

Use a vertical format to subtract the polynomials.<br> 7x2 - 7x + 1<br> - (10x2<br> + 9x – 5)

juin [17]

7x^2 minus 10x^2 is 3x^2

-7x +9x is 2x

Lastly, 1 + -5 is -4

So your answer should be 3x^2 +2x-4. I hope this helps. Also I hope the picture is clear enough to see!
