Answer:x=-3
Step-by-step explanation:
Perimeter is l+l+w+w, or l*2+w*2. We know the width is 4 feet. 26=4*2+l*2
So first, find what 4*2 equals. The answer is 8. So subtract 8 from both sides. 4*2 Cancels out, and 26 changes to 18. Then, divide both sides by 2. The (*2) gets cancelled and 18 becomes 9. The length is 9 FEET.

Step-by-step explanation:
You have to mulitply all the three numbers together to find the area of the figure. But if it is permiter then you add it
8 gallons equals 64 pints
Answer:
No, but x = 4
Step-by-step explanation:
3(7) + 8 - 7 = 5(7) - 4
21 + 8 - 7 = 22
22 = 35 - 4
22 = 31
It is not
How this equation may work is by subtracting the numbers by each side
3x + 8 - x = 2x + 8
2x + 8 = 5x - 4
-8 -8
2x = 5x - 12
-5x -5x
-3x = -12
x = 4
