If solving for x, its x= 1, 11
The answer is x² + 23x + 49
The area (A) of the shaded region is the difference between the area of the rectangle (A1) and the white square (A2).
A = A1 - A2
A1 = (x + 10)(2x + 5)
= 2x² + 5x + 20x + 50
= 2x² + 25x + 50
A2 = (x +1 )² = x² + 2x + 1
A = A1 - A2
= 2x² + 25x + 50 - (x² + 2x + 1)
= 2x² + 25x + 50 - x² - 2x - 1
= x² + 23x + 49
Answer:
I am not too sure but I think the answer would be 6
Step-by-step explanation:
Answer:
8) complementary, 45°
9) supplementary, 5x = 135°, (x+18) = 45°
10) alternate angles, 49°
Step-by-step explanation:
For 8th question
35 + 5x = 90° because the given angles are complementary
5x = 90 - 35
5x = 45
x = 9
For 9th question
5x + x + 18 = 180° because the given angles are supplementary
6x = 180 - 18
6x = 162
x = 27
For 10th question
3x + 1 = 49° because these angles are alternate
3x = 49 - 1
3x = 48
x = 16
The slope is 10
(-5,-9)
(-4,-a)
a=-19
Because the slope is 10, that means when the input increases, the output will increases 10.
