The footage is 1000 square footage
3x + 4y = 31
2x - 4y = -6
*The +4 and -4 in the center of the equation cancel out because 4-4 = 0*
3x = 31
2x = -6
------------
*add like terms*
3x + 2x = 5x
31 - 6 = 25
So now you should have this written on your paper ... > 5x = 25
*Divide by 5 on each side*
5x = 25

5 5
x = 5
Answer:
5
Step-by-step explanation:
maybe because 1.2 × 5 = 6
The perimeter will be the perimeter of the real thing divided by 1.2 .
The area will be the area of the real thing divided by (1.2)² .
The answer is 9 because 9 to the second power is 81 and 81*9 = 729 :)))
