The answer to the question is A
Answer:
Option C: ![$ \sqrt{\textbf{121}} $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B%5Ctextbf%7B121%7D%7D%20%24)
Step-by-step explanation:
Given the side length of a square is 11 units.
Note that ![$ \sqrt{121} = \pm 11 $](https://tex.z-dn.net/?f=%24%20%5Csqrt%7B121%7D%20%3D%20%5Cpm%2011%20%24)
Since, length cannot be negative, we can eliminate - 11.
Hence, the length of the side of the square is 11 units =
.
Hence, the answer.
Answer:
y = (4/7)x² - (24/7)(x)
Step-by-step explanation:
4 = a(-1)² + b(-1)
4 = a - b
0 = a(6)² + b(6)
36a + 6b = 0
b = -6a
4 = a - (-6a)
7a = 4
a = 4/7
b = -24/7
y = (4/7)x² - (24/7)(x)
Midpoint formula = (-9 + 6) / 2 = -3/2
