Step-by-step explanation: To make a line paralle to another, the slope has to be the same such as the "m" in "y=mx+b" the y-intercept or "b" could be different. In this case, the slope is -7. So the question mark should be -7.
Answer:
64 ft²
Step-by-step explanation:
10 ft · 10 ft
100 ft²

6 · 6 = 36
36 ÷ 2 = 18
18 ft² + 18 ft² = 36 ft²
100 ft² - 36 ft²
64 ft²
Answer: 
Step-by-step 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
.
