Answer:
45
Step-by-step explanation:
plug in 3 where the xs are
2(3)(6(3)-5(3))+(3)^2(5(3)-4(3)=45
2(3)=6
6(3)=18
-5(3)=15
(3)^2=9
5(3)=15
-4(3)=-12
Answer:
f(-2) = -15
Step-by-step explanation:
f(x) = 5x-5
Let x = -2
f(-2) = 5(-2) -5
= -10 -5
=-15
C.) x = -4 is the correct answer
Step-by-step explanation:
In order to solve the equation we have to isolate x on one side of equation
Given
7x + 6 = -22
Subtracting 6 from both sides

Dividing both sides by 7

Hence,
C.) x = -4 is the correct answer
