Answer:
Explanation:
To find the area of the shaded region, you must find the area of the larger rectangle [(x+10)×(2x+5)] and subtract the area of the smaller rectangle [(x+1)×(x+1)] from it.
First, you simplify the larger rectangle's area:
(x+10)×(2x+5) =
Then, simplify the smaller rectangle's area:
(x+1)×(x+1) =
Finally, subtract the smaller rectangle's area from the larger rectangle's area:
Therefore, the final answer is
.
