Hey there :)
Let us change the sentence into mathematics:
Area of rectangle = 35 m²
Length of rectangle is 3 m more than twice the width = 3 + 3w
Width = w
We know the area formula of a rectangle
Area = length × width
Dimensions of the rectangle are:
35 = w ( 3 + 2w )
35 = 3w + 2w²
Take all values to one side and equate to 0
2w² + 3w - 35 = 0
Factor:
( 2w - 7 ) ( w + 5 ) = 0
w =
or w = - 5 ( Reject because lengths can never be negative )
Therefore the dimensions are:
Width = 3.5 mLength = 3 + 2 ( 3.5 ) = 10 m
Answer:
add 9 to each side
Step-by-step explanation:
x^2 -6x = 5
Take the coefficient of the x term
-6
Divide by 2
-6/2=3
Square it
3^2 =9
Add 9 to each side
x^2 -6x+9 = 5+9
(x-3)^2=14
The second one? Sorry if you get it wrong I’m not really sure! :3
