Answer: C
<u>Step-by-step explanation:</u>
f(x) = 2x + 1 ⇒ 2x + 1
<u>- g(x) = -(x² - 7) </u>⇒ <u>-x² + 7 </u>
(f-g)(x) = -x² + 2x + 8
Answer:
Hmmm let me solve then I will answer
Answer:
- 9,800,000,000
Step-by-step explanation:
9.8 * 
Simplify 10 with exponent
= -10 with 9 zeroes
Rewrite
= -1,000,000,000
Place back into expression
9.8 * -1,000,000,000
Simplify by multiplying
- 9,800,000,000
Let me know if you have any questions!
Multiply the parentheses then collect like terms
(x+4y+z) (x-7y)
x^2-7xy+4xy-28y^2+xz-7yz
x^2-3xy-28y^2+xz-7yz
