4/30=x/48
30x=4x48
30x=192
x=6.4

Step-by-step explanation:
(x-2)(x+7)=90
x^2 +5x -14=90
x^2 +5x -14 -90=90-90
x^2 +5x -104=0
factor it out
(x−8)(x+13)=0
so 8 or -13
The art sculpture was 70 inches aka 5.9feet tall and if we round it well it would be 6feet so that would be its highest piont
The answer is g^-1= x^2/2 + 1/2
