Answer:
x^2 +23x +49
Step-by-step explanation:
First we find the area of the rectangle as though the small square were not cut out of it
A = (x+10) (2x+5)
Foil
2x^2 +5x+20x+50
2x^2 +25x+50
Then we find the area of the small square
A = (x+1) (x+1)
FOIL
x^2 +x+x+1
x^2 +2x+1
Then we subtract the small square from the large rectangle to find the area of the shaded region
2x^2 +25x+50 - (x^2 +2x+1)
Distribute the minus sign
2x^2 +25x+50 - x^2 -2x-1
x^2 +23x +49
According to your statement, it's expression would be:
9 + 2x
So, your correct answer is 9 + 2x
