Answer:
The width of the rectangle is <u>7 feet</u>.
Step-by-step explanation:
Given:
The perimeter of a rectangle is 54 feet, and the length is 13 feet more than the width.
Now, to find the width of the rectangle.
Let the width be 
So, the length is 
Perimeter = 54 feet.
Now, to get the width we put formula:




<em>Subtracting both sides by 26 we get:</em>

<em>Dividing both sides by 4 we get:</em>

Therefore, the width of the rectangle is 7 feet.

Answer:
1 1/30 gallons, or 31/30 gallons of paint
Step-by-step explanation:
Before these fractions can be added together they have to have a common denominator. The Least Common Multiple of 2, 3, and 5 is 30, so
1/3 = 10/30 1/5 = 6/30 1/2 = 15/30
10/30 + 6/30 + 15/30 = 31/30, or 1 1/30
Answer:
B. 3 square feet
Step-by-step explanation:
The formula for surface area is:
2lw+2lh+2wh
Box F's surface area is just plugging in those variables
2(3)(3)+2(3)(3)+2(3)(3)=54
Box J's surface area is the same way
2(2)(4.5)+2(2)(3)+2(4.5)(3)=57
The difference is 57-54=3
The answer is B. 3 square ft
