Answer:
(f + g)(x) = 3x² + x + 5
(f - g)(x) = 3x² - x - 3
Step-by-step explanation:
(f + g)(x) → f(x) + g(x) → <u>3x² + 1</u> + <u>x + 4</u>
Combine like terms and you get: 3x² + x + 5
(f - g)(x) → f(x) - g(x) → <u>3x² + 1</u> - (<u>x + 4</u>)
Remember to distribute the neg. everything in the parentheses. Combine like terms and you get: 3x² - x - 3
It is 5 since u need to jump 5 times 4,8,12,16,20=5 times 4
Answer:
P=16+2x
Step-by-step explanation:
The formula for finding the perimeter of a rectangle is P=2l+2w.
Plug the length of 8 and the width of x into the formula.
You'll get P=2(8)+2(x).
Multiply. 2•8=16 and 2•x=2x.
Your expression is P=16+2x.
I hope this helps.
