Ответ:
14> Volume of a rectangular prism = length * width * height
= (3+1/4) * (2) *(1 + 1/2) ft^3
=(13/4)*2*(3/2) = 39/4 = 9 3/4 ft^3 [Option D]
15> We have the following coordinates for vertices of our rectangle:
( - 10, 2) (15, 2) (15, 5) (-10, 5)
You might want to graph it if this helps. But the gist is that opposite sides of rectangles are the same. So freezing either the x and y coordinate and subtracting from the y coordinate and x coordinates we get:
5 and 3. 5>3 therefore 5 is the answer.[ Option A ]
Hope this helped:)
