Answer:
The Correct Answer is B
Step-by-step explanation:
It is a pattern so 2*3=6
3 times 4 is 12
4 times 5 is 20
5 times 6 is 30
6 times 7 is 42
so, 9 times 8 is 72.

Answer:
x = 12
Step-by-step explanation:
Equation: 0.52(x) + 0.72(4) = 0.57(x + 4)
0.52(x) + 0.72(4) = 0.57(x + 4) 
Multiply
0.52x + 2.88 = 0.57x + 2.28 Subtract 0.52x from both sides
2.88 = 0.05x + 2.28 Subtract 2.28 from both sides
0.6 = 0.05x Divide all sides by 0.05
x = 12

Relative extrema occur where the derivative is zero (at least for your polynomial function).
So taking the derivative we get

This is a 3rd degree equation, now if we are working with complex numbers this equation is guaranteed to have 3 solutions by the fundamental theorem of algebra. But the number of real roots are 1 which can be found out by using Descartes' rule of signs. So the maximum number of relative extrema are 1.</span>
