F(1)=0 so x=1 is a zero => x-1 is a factor 1 | 1 -8 -23 30 | 1 -7 -30 --------------------- 1 -7 -30 | 0 x^2-7x-30 is another factor x^2-7x-30=(x-12)(x+5) x=12, x=-5 our roots too s0 1+12+(-5)=13-5=8

Answer:
75cm^2
Step-by-step explanation:
When you say a rectangular prism, it means it has the base has 4 sides of which opposite sides are equal as a rectangle. This sides substends so we have a total of 6 surfaces in this prism.
This 6 surfaces has 3 surface area the same.
The surface area = sum of area of all faces.
325= 50 + 50 + 37.5 + 37.5 + 2x; where X is the area of the surface unknown.
325= 100+ 75 + 2x
325-175= 150
150= 2x
X= 150/ 2 = 75 cm^2
