Answer:
10 +2x
Step-by-step explanation:
Put the given values into the perimeter formula and simplify.
P = 2(L+W)
P = 2(5 + x)
P = 10 +2x . . . . the perimeter of the rectangle in units
Answer:15 inches by 27 inches
Step-by-step explanation:
A rectangle has a width of 5 inches and a length of 9 inches. This means that the original length of the rectangle is 9 inches. The original width of the rectangle is 5 inches.
The rectangle was dlated by
a scale factor of 3. It means that the dimensions of the length of the rectangle and the width of the rectangle were increased 3 times.
The new length of the rectangle would be 3 × original length. It becomes 3×9 =27 inches
The new width of the rectangle would be 3 × original width. It becomes 3×5 =15 inches
Answer:
Step-by-step explanation:
so let’s say x is the length. Then the width will be 3x-4. You add them together and multiply by two. The perimeter is 72 so the equation equala 72.
Equation:
(x+3x-4)*2=72
(4x-4)*2=72
8x-8=72
8x=80
x=10
length:10
width:26
