2 ( x + 1 ) = 12
Use distributive property:
2x + 2 = 12
Subtract 2 from both sides:
2x = 10
Divide both sides by 2:
X = 5
Answer:
10w+8
Step-by-step explanation:
-10(-w)+8
10w+8
Short side length = x
Medium side = x + 7
Long side = 5x
Total 49, so
x + x + 7 + 5x = 49
If you combine like terms:
7x + 7 = 49
Subtract 7 from both sides
7x = 42
Divide both sides by 7
x = 6 inches.
