Answer: find the answer in the explanation.
Step-by-step explanation:
You are given that the sides of a rectangle are a number and 4 less than that same numbers.
Let the length side = L
And width side = L - 4
The dimensions of the rectangle will be
Area = length × width
L × ( L - 4 )
Open the bracket
L^2 - 4L
The verbal expression here,
Perimeter = L + L + W + W
Substitute all the parameters into the formula
56 = L + L + L-4 + L-4
56 = 2L + 2L - 8
56 = 4L - 8

Answer: x = 7</h3>
Explanation:
Segment addition postulate
CD+DE = CE
this basically is the idea of gluing smaller pieces together to get a larger structure. We can go in reverse to break up a large item into smaller bits. This is assuming there is no leftovers, overlaps, or parts wasted/lost.
CD = 9
DE = 3x+6
CE = 36
----
CD+DE = CE
9+3x+6 = 36
3x+15 = 36
3x = 36-15
3x = 21
x = 21/3
x = 7
-----
If x = 7, then
DE = 3x+6 = 3*7+6 = 21+6 = 27
and
CD+DE = 9+27 = 36 = CE
confirming our answer
Answer:
The second 4 wheeler gets better mileage
Step-by-step explanation:
First 4 wheeler:
52mi - 5gal
Second 4 wheeler:
21mi - 2 gal
To compare we have to make sure everything is equal so,
5÷2 = 2.5
so,
second 4 wheeler:
21*2.5=52.5 , 2*2.5=5
52.5mi - 5gal
52<52.5
