Answer is x² + 2x + 5
<u>Step-by-step explanation:</u>
Step 1:
Add the two polynomials
⇒ (2x + 7) + (x² - 2) = 2x + 7 + x² - 2 = x² + 2x + 5
Remember you can do anything to an equation as long as you do it to both sides
2b+3c=14
minus 3c both sides
2b=14-3c
divide both sides by 2
It's $7.00 for it to be an average of $8.00 so B. *took the test*
