The length of a rectangle is twice its width. The perimeter is 30. Find its dimensions
bogdanovich [222]

Answer:

Step-by-step explanation:

The width of the rectangle = x

Therefore the length of the rectangle = 2x, as it is twice its width

We know that the perimeter of a rectangle = 2 × (length + width)

So since the perimeter equals to 30, then we can form the equation:

                                      2×(2x+x) = 30

                                          2×(3x) = 30

                                                6x = 30

                                                   x = 5

width of the rectangle = x = 5

length of the rectangle = 2x = 2×5 = 10

If there is an unit which is in the question, remember to add it to the end of the answer. As you have not written any units in the posted question, I will leave it as it is.

Hope this helps :)

Simplify the expression: 7y+3x+3-2y+6<br> Is it 9y+3x+9???
Sonbull [250]
Step 1) Combine like terms/variables.

7y and -2y are similar, combine them.
7+(-2y)=5y

3x has no similar variables, so it stays the same

3 and 6 are similar, without variables, combine them.
3+6=9

The final answer is 5y+3x+9

lyudmila [28]
Average rate of change is the same as finding slope between a line on a non- linear function.
Using the ordered pairs
(5,10) and (8,1)
(10-1)/(5-8) = 9/-2 = -9/2
