Width of the rectangle is 14 ft
Step-by-step explanation:
- Step 1: Let the width of the rectangle be x. Then length = 8 + x. Perimeter = 72 ft.
Perimeter = 2(length + width)
72 = 2 (8 + x + x)
72 = 16 + 4x
4x = 56
x = 56/4 = 14
∴ Width of the rectangle is 14 ft
To find the inverse of an equation simply switch the X and y coordinates and solve for the new Y coordinate.
Y = 2x + 4
X = 2y + 4
X - 4 = 2y
X-4/2 = 2y/2
Y = X - 4/2.
Answer:
Step-by-step explanation:
a^2 + b^2 = c^2.
if you draw out the triangle, you can substitute numbers into an equation.
6^2 + b^2 = 8^2
36 + b^2 = 64
b^2 = 64 - 36
b^2 = 28
b = 
54
9²-3×9
81-27=54
