Answer:
W = 6 feet
L = 15 feet
Step-by-step explanation:
The perimeter of the rectangle is the length of the outer boundary.
If length is defined as L and width is defined as D,
Perimeter = 2(L + W)
Perimeter is given to be 42 feet.
2(L + W) = 42
(L + W) = 21 ------------------(1)
Also , Its length, L, is three feet more than twice its width, W.
L = 2W + 3 -------------------(2)
Solve (1) and (2) ,
3W + 3 = 21
W = 6 feet
L = 15 feet
The sum is one thousand four hundred ninety-nine.
Answer: 22 feets of the border should be purchased
Step-by-step explanation:
A triangular flower bed (space for planting flowers) needs a thin metal border all the way around it. We want to look for the number of feet of the border that should be purchased. In this case, we are dealing with the distance round the border which is a triangle. The distance round the border is also known as the perimeter of the border. Therefore,
The perimeter of a triangle is the sum of all three sides.
The dimension of the sides are given as 7 feet, 6 feet, 9 feet long. Therefore, the perimeter is
7 + 6 + 9 = 22 feets
Answer:
Alright! BTW, the answer to the question is D :)
Step-by-step explanation:
Reflecting across the x-axis, the x-coordinate ALWAYS remains the same, but the y-coordinate is transformed into its opposite. If you forget this, fold along the x line, and you should be able to figure it out. Reflecting across the y-axis, the y-coordinate ALWAYS remains the same, but the x-coordinate is transformed into its opposite. If you forget this, fold along the y line, and you should be able to figure it out.
Hope I helped!
