Answer:
16x³ + 9x² + 9x + 13
Step-by-step explanation:
Given
6x³ + 8x² - 2x + 4 and 10x³ + x² + 11x + 9
Sum the 2 expressions by adding like terms, that is
= (6x³ + 10x³) + (8x² + x²) + (- 2x + 11x) + (4 + 9)
= 16x³ + 9x² + 9x + 13
Step-by-step explanation:
2(3x-5)=5x-3
6x -10 =5x -3
x=7
Your answer is

because the numbers raised to negative powers must be flipped over the divisor to become positive. Then, when multiplying 2 and z, you add their exponents.
Since EF=FG, you can set 6x - 10 = to 3x + 11

Then add like terms

so,

Now you can divide by 3 to get

:)
then put it back into
