Answer:
Width = 12
Length = 16
Step-by-step explanation:
Width = x
Length = x + 4
2x + 2(x+4) = 56
2x + 2x + 8 = 56
4x = 56 - 8
x = 48/4
x = 12
When two dice are thrown simultaneously, thus number of event can be 62 = 36 because each die has 1 to 6 number on its faces. Then the possible outcomes are shown in the below table.
First, distribute the minus sign across the second set. So you have:
x - y + 1 - x - y + 1
Now, we combine like terms:
x-x=0
-y-y=-2y
1+1=2
So we have -2y+2
Hope that helps.
