perimeter = 2L + 2W
L=8+w
perimeter = 2(8+w) +2w
80 =16+2w+2w
80 = 16 +4w
64 =4w
w=64/4 = 16
l=16+8 =24
length = 24 feet
width = 16 feet
check 2(24) +2(16) = 48 + 32 = 80
Answer: 5y + x
Step-by-step explanation: As you first step to this problem, change all your minus signs to plus negatives.
To simplify, we can only combine what are called our like terms and in this problem, we have one y-term and we have a pair of like terms in our x-terms.
So let's start by combining our y-terms.
13y + -7y simplifies to 5y.
Now we have one x-term so we have 5y + x.
8n+52=12(n+2)
distribute
8n+52 = 12n+24
subtract 8n from each side
52=4n +24
subtract 24 from each side
28 = 4n
divide by 4 on each side
7=n
Answer: i dont know, gook luck
Step-by-step explanation:
Answer: 6
Step-by-step explanation:
Slope is found by doing:
(x1 and y1 must be from the same ordered pair and x and y must be from the same ordered pair, however point (x1,y1) and (x,y) can be used interchangeably)
Let us say that (x1,y1) is (3,18)
And (x,y) is (5,30)
