What is .52,57% and 2/5 from least to greatest
Alekssandra [29.7K]
Concert 2/5 into a percent 5*20 = 100 (denominator) so 2* 20 =40
40/100 is 40%
I'm guessing you accidentally put the dor in front of 52 so it would be 40 at least and 52.57 at greatest

If the perimeter of a rectangle is 6x^2-2x+14 and the length is x^2-x+8 what is the measure of the width?
s2008m [1.1K]

Answer:

w = 2x^2-2x+15

Step-by-step explanation:

Since the formula to find the perimeter is P=2l+2w, use this to set up your equation:

6x^2-2x+14 = 2(x^2-x+8) + 2w

Then, distribute the 2 to everything inside the parentheses.

6x^2-2x+14 = 2x^2-2x+16 + 2w

Subtract 2x^2-2x+16 from both sides, leaving you:

4x^2-4x+30 = 2w

Divide 2 from both sides.

2x^2-2x+15

The answer is 2x^2-2x+15
