G(f(x))= (7x+8)^4
g(f(x))= (7(0)+8)^4
=(0+8)^4
=8^4
=8•8•8•8
=4,096
Answer:
5.7a - 18.2b
Step-by-step explanation:
<u>Step 1: Write the equation</u>
(12.2a + 9.7b) – (18.1b – 0.2a) – (6.7a + 6.8b)
<u>Step 2: Open all brackets</u>
12.2a + 9.7b - 18.1b + 0.2a - 6.7a - 6.8b
<u>Step 3: Arrange all 'a' together and all 'b' together</u>
12.2a + 0.2a - 6.7a + 9.7b - 18.1b - 6.8b
<u>Step 4: Simplify</u>
5.7a - 18.2b

Answer:
7 pieces of homework
Step-by-step explanation:
This is an algebra problem. We first need to set up our algebra equation and we are going to find X (The amount of homework Richard submitted)
The algebra equation would be
X+X+2=12
*Combine like terms*
2X+2=12
Subtract 2 to both sides
2X=10
X=5
That means that Richard did 5 pieces of homework. We are not done yet because we want to find the amount of homework Isaac did. Earlier in the problem, it said that Issac did 2 more pieces of homework than Richard. Take Richard's number, 5 and add to 2 to it to get 7 pieces of homework.
