Find the side length of a square with the given area. 121in(2 exponent) a.) 11 inches. b.) 60.5 inches. c.) 1,331 inches. d.) 14,641 inches.

A.) 11 inches

Step-by-step explanation:

There's a couple of ways to do this. If you know how to take a square root, use this way: is equal to . So that would mean that . Canceling it out (the square root of a square equals the original base), it equals 11. So the side length would be 11 inches.

Remember, we know the AREA and need to find the side length, so this is why we don't square 121 to get 14,641. 121 is the area and not the side length.

Hope this helps.

y = 5x + 17

step-by-step explanation:

a perpendicular line will be the opposite reciprocal slope of the given equation.   the slope given is -1/5 so the opposite reciprocal is 5

find b:

7 = 5 (-2) + b

7 = -10 + b

17 = b

write equation

y = 5x + 17
