The thing that's wrong with the equation is that 2 shouldn't be multiplied by 4 but should have been added.
<h3>How to illustrate the information?</h3>
From the information given, it can be seen that the equation is:
(3x²)(-2x⁴) = 3(-2)x² × x⁴ = 6x^8
Based on the information above, this calculation is incorrect. The correct calculation will be:
(3x²)(-2x⁴) = 3(-2)x² × x⁴
= -6x^6
Therefore, the multiplication should be an addition of the power.

Answer:
its b .
Step-by-step explanation:
Let us say that:
K = age of Kristen
B = age of Ben
From the problem, we make the equations:
eqtn 1: K + B = 32
eqtn 2: (K – 4) = 2 (B – 4)
Simplifying eqtn 2:
K – 4 = 2 B – 8
K = 2 B – 4
Plugging in this to eqtn 2:
(2 B – 4) + B = 32
3 B – 4 = 32
3 B = 36
B = 12
From eqtn 2:
K = 2 B – 4 = 2 (12) – 4 = 20
So Kristen is 20 while Ben is 12.
