Answer:
multiply by 2
Step-by-step explanation:
5x2=10
10x2=20
Adding 4 to both side is wrong he has to be subtract 4 to both side
Answer:
The slope is 2.
Step-by-step explanation:
The formula for slope is m = (y2-y1)/(x2-x1)
If we choose the points (0,2) and (1,4) we can plug these into our slope equation.
(4 - 2) / (1 - 0) = 2/1 = 2
Answer: The length of the rectangle is 15 inches
Step-by-step explanation:
Let L represent the length of the rectangle.
Let W represent the width of the rectangle.
The perimeter of a rectangle is expressed as 2 length + 2 width
Perimeter = 2(L + W)
The rectangle has a perimeter of 52 inches. It means that
2(L + W) = 52
L + W = 52/2 = 26 - - - - - - - 1
The length of the rectangle is 4 inches more than its width. It means that
L = W + 4
Substituting L = W + 4 into equation 1, it becomes
W + 4 + W = 26
2W = 26 - 4 = 22
W = 22/2 = 11
L = W + 4 = 11 + 4 = 15
