D'andre was trying to make a rectangular frame that had a width of 24 inches and a length of 70 inches. He wanted to ensure his shape contained right angles, so he measured the diagonal and found that it was 74 inches long. Did D'andre construct a rectangle? Why or why not?

yes

the sum of the squares of the width and length is equal to the square of the diagonal

Step-by-step explanation:

The Pythagoras theorem : a² + b² = c²

where a = length

b = base

c =  hypotenuse

24^2 + 70^ = 576 + 4900 = 5476

square root = 74

d? maybe

step-by-step explanation:

-362

step-by-step explanation:

(12)(4)+2(12)-34(12)+2(12)-3

  \/         \/         \/         \/

  48 +   24 -   408 + 24 - 3

      \   /               \   /

          72     -     432 - 3 = -363
