Answer:

24 feet

Step-by-step explanation:

Since the shape is a square we can identify that the equation to find the area of it is Side×Side= Area. Now we were given the area, 36 square feet. Next we need to identify the equation for perimeter because this is what they are asking for. Perimeter for a square is 4×Side=Perimeter or Side+Side+Side+Side=Perimeter. Now we need to find the Length of a side of the square so we can plug that value into the perimeter equation... To do this u take the 36 square feet and square it. That gives u the length of ONE side of the square... Next u plug in 6 (THE LENGTH OF THE SIDE) into the perimeter equation. So, 6+6+6+6=24. Hope it helped!

Which steps could be part of the process in algebraically solving the system of equations, y + 5x = x2 + 10 and y = 4x – 10? Che

That would be :
4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y)

PROOF: y + 5x = x² + 10
 (4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10


0 = x2 – 9x + 20 (liked terms are grouped and simplified)

PROOF: 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20

Solving:
x² - 9x + 20 = 0

x² - 5x - 4x + 20 = 0

(x - 5) (x - 4) = 0

⇒ x = 4 (as question says) OR x = 5
