Me i been struggling with these two questions

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:)  

answer: $201

step-by-step explanation: to get the answer, you first get 3 nieces that he sold and multiply it by 67 and get $201, so he earned $201 selling his nieces.

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3
