Step-by-step explanation:
x + 7 = 18
-7 both sides
x = 11
Length = 17 feet, Width = 5 feet
Given:
The area of a rectangular wall of a barn is 85 square feet.
Its length is 12 feet longer than the width.
Question asked:
Find the length and width of the wall of the barn.
Solution:
Let width of a rectangular wall of a barn =
<u>As length is 12 feet longer than the width.</u>
Length of a rectangular wall of a barn =
As we know:
Subtracting both sides by 85
As width can never be in negative, hence width of a rectangular wall of a barn = = 5 feet
Therefore, length and width of the wall of the barn is 17 feet and 5 feet respectively.
y = 30x + 20
y = mx + b
find b
b=20
find m
m=30
