Define x and y:
----------------------------------------------------------------
Let the length be x.
Let the width be y.
----------------------------------------------------------------
Formula:
----------------------------------------------------------------
Perimeter = 2(Length + Width)
----------------------------------------------------------------
Construct equations and solve for x and y:
----------------------------------------------------------------
2x + 2y = 56 ---------------------- (1)
2(x+8) + 4y = 82 -----------------------(2)
----------------------------------------------------------------
From equation 1:
----------------------------------------------------------------
2x + 2y = 56
x + y = 28
x = 28 - y
----------------------------------------------------------------
From equation 2:
----------------------------------------------------------------
2(x+8) + 4y = 82
2x + 16 + 4y = 82
2x + 4y = 66
x + 2y = 33
----------------------------------------------------------------
Substitute x = 28 - y into equation 2:
----------------------------------------------------------------
x + 2y = 33
(28 - y) + 2y = 33
28 - y + 2y = 33
y = 5
----------------------------------------------------------------
Substitute y = 5 into equation 1:
----------------------------------------------------------------
x = 28 - y
x = 28 - 5
x = 23
----------------------------------------------------------------
Find Length and Width
----------------------------------------------------------------
Length = x = 23 m
Width = y = 5m
----------------------------------------------------------------
Answer: Length = 23m and Width = 5m
----------------------------------------------------------------
Like what is you trying to say explain
Answer:
Step-by-step explanation:
So remember we must start with the negative side.
-9, -6, -3, 0, 1, 4, 8
The greatest negative number (-9) is the lowest of all.
Answer:
| x + 4 | = -1 No solution
Step-by-step explanation:
3 | x + 4 | + 12 = 9
Subtract 12 from both sides: 3 | x + 4 | = -3
Divide both sides by 3: | x + 4 | = -1
Absolute value cannot be negative, so there is no solution.
Answer:
n = 8
Step-by-step explanation:
-2n - 13 = -3n - 5
-2n + 3n = -5 + 13
n = 8
Hope this helps. Have a nice day!
