Answer:
width = 15 inches
length = 36 inches
Step-by-step explanation:
To solve you need to find the width...
width = w
length = 2w + 6
the perimeter is all the way around the area, so..
2w + 2(2w + 6) = 102
because there are 2 widths and 2 lengths in a perimeter.
Solve for w:
2w + 4w + 12 = 102
subtract 12 from both sides and combine like terms...
6w = 90
divide both sides by 6...
w = 15
the width = 15, and the length = 2(15) + 6 = 36
Answer:
X equals to -11
Step-by-step explanation:
The richest president in the world is Sebastian Pinera, President of Chile with $2.4 billion.
12x+7x+8y+12^2+y+12=19x+9y+24^2
2(3r+7)−(2+r)
Use distributive property:
6r + 14 - 2 - r
Simplify by combining like terms:
5r +12
