The slope is 7 and the y-intercept is (0,9)
Answer:
C:44
Step-by-step explanation:
To find the perimeter, you do length+length+width+width
So
13+13+9+9=44
Another formula:
L2+W2 (length x 2 + width x 2)
Yeah yeah I can

2(x - 5)² + 13 = 31
2(x - 5)(x - 5) + 13 = 21
2(x(x - 5) - 5(x - 5)) + 13 = 21
2(x(x) - x(5) - 5(x) + 5(5)) + 13 = 21
2(x² - 5x - 5x + 25) + 13 = 21
2(x² - 10x + 25) + 13 = 21
2(x²) - 2(10x) + 2(25) + 13 = 21
2x² - 20x + 50 + 13 = 21
2x² - 20x + 63 = 21
<u> - 21 - 21</u>
2x² - 20x + 42 = 0
2(x²) - 2(20x) + 2(21) = 0
<u>2(x² - 20x + 21)</u> = <u>0</u>

x² - 20x + 21 = 0
x = <u>-(-20) +/- √((-20)² - 4(1)(21))</u>
