Answer:
P = 4x - 6
Step-by-step explanation:
In a given rectangle, the shorter side is 3 less than the longer side.
Let the longer side is the length of the rectangle L and the shorter side of the rectangle is the width of the rectangle W.
Then from the condition given we can write that L = W + 3 ....... (1)
Now, perimeter of the rectangle is given by P = 2(L + W)
So, from equation (1) we can write P = 2(L + L - 3) {Since W = L - 3}
⇒ P = 2(2L - 3) = 4L - 6.
Now, if we represent L as the variable x, then the expression for perimeter P = 4x - 6 (Answer)
Answer:
6
Step-by-step explanation:
The equation for this problem would be c = (20 + 8) / 2 - 8. Add 20 and 8 to get 28, divide 28 by 2 to get 14, then subtract 8 to get 6.
