From the equations given above, you can graph them by the slope and the y-intercept. I will be solving this by substitution method. It will be giving the same values as with graphing. We do as follows:

-2x + 30 <span>= -x + 21
-x = -9
x = 9
y = -9+21 = 12

Hope this helps. Have a nice day.

AlladinOne [14]

Answer:

The length of each side of the base is $229\ m$

Step-by-step explanation:

we know that

The area of a square is equal to

$A=b^{2}$

where

b is the length side of a square

In this problem we have

$A=52,441\ m^{2}$

so

substitute in the formula

$52,441=b^{2}$

Square root both sides

$b=\sqrt{52,441}\ m$

$b=229\ m$
