So you only have 3 sides so the perimeter will be length+2width instead of 2length+2 width
l+2w= perimeter
you know the length of the longest side is 15
15+2w = perimeter
and you also know that he is using 31 feet of fencing
15+2w = 31
2w = 16
w=8
Answer:
-3 is the slope of the line
Step-by-step explanation:
Since the slope formula is y = mx +b.
M - slope of line
B - y intercept
y - is the y value of the coordinate, once u plug in x this is your answer
So since m is the slope and the equation is y + -3x +2 the slope of the line is -3
20 can be divided by 2 twice, with 5 remaining
20 can be divided by 4 once, with 5 remaining
20 can be divided by 5 once, with 4 remaining
20 can be divided by 10 twice
20 can be divided by 20 once
hope this helps
