Answer:
The answer is 27
Step-by-step explanation:
The reason being, you can solve this 2 ways.
1) Combine like terms, 7a-4a = 3a.
Now just substitute (a=9) into 3a.
3 * (9) = 27.
2) Or just substitute a = 9 into the original expression.
7 * (9) - 4 * (9)
= 63 - 36 = 27
Answer: 12(a+5)
Step-by-step explanation: factor out 12 from the expression
ANSWER 12(a+5)
Answer:
Solve for f.
f(−4)=−3x+6
Step 1: Divide both sides by -4.
−4f/-4 = −3x+6/−4
f=3/4x + −3/2
Answer:
f= 3/4x + −3/2
5(-2) = -10, so 5(-2)(-11) = (-10)(-11) = 110
