Answer:
Step-by-step explanation:
1) f(x) =0 : x² +9 =0 means x² = -9 ..no solutions in R
2)g(x) =0 : (x-9)² =0 means x-9= 0 ..... single solution : 9
3) h(x)=0 : (x+1)² - 9 = 0 means (x+1)² = 3² so x+1=3 or x+1 = -3
two solutions : 2 and -4
s = ∛756
The volume of a cube is found by V = s³. To solve for the side of a cube with a specific volume, we use inverse operations to find it. s = ∛V. If the volume is 756 then the s = ∛756.
The choice B.
