12 I think, because area = base times height, so if you work backwards and divide 84 by 7 it equals 12
The value of (fg)(x)= 3x³+ x²
<h3>What is function?</h3>
An expression, rule, or law that defines a relationship between one variable (the independent variable) and another variable (the dependent variable).
Given:
f(x) = -3x+1
g(x) = 
Now, (fg)(x)
=f(x) * g(x)
= (-3x+1) * (
)
=-3x³+ x²
Hence, (fg)(x)= 3x³+ x²

Answer: 3
Step-by-step explanation:
12C - 4 = 14C - 10
12C - 14C = - 10 + 4
- 2C = - 6
C = <u>- 6</u>
-2
C = 3
No, JN is not paralle to KM
The term in that equation is 3x 7x and -9 hope this helps
