Which of the following is equal to the rational expression below when x=11?

topjm [15]

Our first expression is equal to zero:
$\frac{x^2-121}{x+11}= \frac{11^2-121}{11+11} = \frac{121-121}{22}=0$
So we simply find the expression that is equal to zero.
The final answer is a.
$x-11=11-11=0$

Dima020 [189]

Well, since she bought 3.42 pounds of green apples, then you can subtract 3 lbs off of that, so she bought .42 lbs of green apples, and 2.19 lbs red apples
So now, you just need to add .42 and 2.19
.42 + 2.19 = 2.61, so she has 2.61 lbs of apples left
Hope this helped!
