Answer: 20x-6 = 34
Step-by-step explanation:
Given: The length of rectangle is represented by 8x - 3.
The width of the rectangle is represented by 2x.
The perimeter is 34 inches.
Perimeter of rectangle = 2 (length + width)
Perimeter of rectangle = 2 (8x-3+2x)
Perimeter of rectangle = 2 (10x-3)
Perimeter of rectangle = 20x-6
Thus , the required equation that represent the perimeter: 20x-6 = 34
I suppose that the question is 17.5 %.
To increase an amount by a percentage, the multiplier is given by (100 + %)/100
Therefore, to increase an amount by 17.5%,
the single multiplier is given by (100 + 17.5)/100 = 117.5/100 = 1.175
Answer:
1:4
Step-by-step explanation:
Δcde is smaller than Δsrt by a factor of 4
So in a ratio Δcde : Δsrt it’s equal to 1:4
This is an example
Your length of the rectangle is 2 times the width.
Let length = 2x
Let width = x
Now your area = 450m^2
2x.x = 450 ("." means multiply)
2x^2 = 450
Therefore x^2 = 225
Therefore x= 15
If your x=15 , then you know your width.
Length = 2x (2 x 15 = 30)
Therefore:
Length = 30m
Width = 15m
Hope that helped! :)
