Answer:
x = 3 2/3
Step-by-step explanation:
Given
3x - 4 = 7
Add 4 to both sides of the equation
3x - 4 + 4 = 7 + 4
3x = 11
Divide both sides by 3
3x/3 = 11/3
x = 3 2/3
Answer:
Width = 16 m
Length = 4 m
Step-by-step explanation:
The area of rectangular is 64m² the length of the pool is 12 m less that the width . The situation can be represented by the equation x
Area of a rectangle = Length × Width
L = W - 12
Hence:
64 = (W - 12) × W
64 = W² - 12W
W² - 12W - 64 = 0
Factor using
(W + 4)(W - 16) = 0
Width = 16m
Length = W - 12
Length = 16 m - 12 m
= 4 m
