The greatest common factor is 3 I'm pretty sure.
This problem cannot be solved unless we are given figure NPQR is a rhombus.
In that case, then all sides are equal, meaning
5x+16=9x-32
Solve for x
9x-5x=16+32
4x=48
x=12
Each side (including PQ) then equals 5x+16=5*12+16=76
(325-120)/2.5=2050/25=82

Perimeter of rectangle = all sides added
= 3+3+7+7 =20
volume of sphere = 4/3 x π x r(cubed)
= 4/3 x π X 4(cubed)
= 268.08257
area of triangle = base x height / 2
= 5 x 6 / 2
=30/2 =15
volume of pyramid = base height x base width x height / 3
= 300
side of triangle ---> use Pythagoras theorem so a(squared) + b (squared) = c(squared)
4(squared) + 3(squared) = c(squared)
16 + 9 = c(squared)
25 = c(squared)
c = 5
