Answer: D. 4<em>x</em>^2
<em>Hope this helps!</em>
The diagonals of a square bisect one another and are perpendicular.
so 21x+ 16.5 = 90
subtract 16.5 from each side
21x = 73.5
divide by 21 on each side
21x/21 = 73.5 /21
x = 3.5
Hi there
Replace the blank space by x
so x/7 > 800
All you have to do is cross-multiply
x > 7*800
x> 5600
I hope that's help !
