Answer:
C. 28 = (2x - 1)(x)
Step-by-step explanation:
Given :
There is a rectangular swimming pool.
Width of swimming pool is x
Length is one less than twice the width
Area of the swimming pool is 28 sq ft.
To Find : Equation could be used to model the area of the swimming pool.
Solution:
Since we are given that Length is one less than twice the width.
And width is x (given)
So, length = 2x-1
Area of the swimming pool is 28 sq ft.
Now ,
Formula of area of rectangle : Length*Width
⇒28= (2x-1)(x)
So, equation used to model the area of the swimming pool: 28= (2x-1)(x)
Hence Option c is correct.
Answer:
x=5
Step-by-step explanation:
14x-35=4x+15
14x-35+35=4x+15+35
14x=4x+50
14x-4x=4x+50-4x
10x=50
x=5
