Step-by-step explanation:look it up
F + g means adding both f(x) and g(x) together
<span>f(x)=x^2 - 8x and g(x)= x+11 find f+g
f(x) + g(x)
x^2 - 8x + x + 11
Combine like terms together...
x^2 - 7x + 11</span>

Answer:
It would be 9.6 inches after 4 weeks.
The expression you would use is 5 + 2.5 × ww = ?
Step-by-step explanation:
At the beginning of spring, Eva planted a small sunflower in her backyard. When it was first planted, the sunflower was 5 inches tall. The sunflower then began to grow at a rate of 2.5 inches per week. How tall would the sunflower be after 4 weeks? How tall would the sunflower be after ww weeks? Write an expression.
So the sunflower was 5 inches tall to start off.
First you need to do 2.5 times 4.
Which is 9.6 inches after 4 weeks.
The expression you would use is.
5 + 2.5 × ww = ?
First you would have to get them to have the same denomitator so 2 3/4 is the same as 2 6/8 but u cant subtract 1 by 6 so u move 1 8/8 over from 5 1/8 and get 4 9/8 and then u subtract and get 2 3/8
