Answer:
C) 12.2 cm
Step-by-step explanation:
To find the area of a square, you multiply length and width, which for a square, are the same. So to find the length of one of its sides, you have to take the square root of the area.

X intercept is (1,0)
y intercept is (0,-4)
Total marks C needs to get = 92 x 4 = 368
Least grade (fourth quarter) = 368 - 88 - 91 - 90 = 99
2503 is the answer, you can use a calculator to find this by simply plugging it in or use the long division method
