Answer:
6x^2 + 4x
Step-by-step explanation:
g(x) + f(x)
= -8x^2 - 3x + 5 + 2x^2 + 7x - 5
= -8x^2 + 2x^2 - 3x + 7x + 5 - 5
= - 6x^2 + 4x
No. We claim that

and use algebra to prove the statement.
Let

. Multiply this by ten to get

. Subtract the initial equation to give

and divide by

to see that

. Substituting into the original equation gives

, proving the desired statement.
Answer:
= 70f - 9g
Step-by-step explanation:
1. Remove parentheses
2. Multiply the numbers
3. Multiply the numbers
Is it subtract 228? if so then 3-5 equals -2. -2-8 equals -10. -10-228 equals -238
Divide 5 by 4 and the left over Is the top of the fraction then your divisor is on the bottom so it would be 1 and 4/5.
