Answer:

  B)  5x/x +3/x

Step-by-step explanation:

Choice B is the only choice showing a correct denominator: x.

Here, the "first step" is apparently to divide <em>each term</em> by the denominator. This is reasonable when the denominator is only one term.

(I'd say the first step is to divide the <em>first term</em> by the first term of the denominator.)

Root of Y2-Y1 squared is what we are left with
Root of -2- -3 squared
Root of 1 squared
Root of 1

PLZZZZZ HELP MEH ILLLL MARK AND 100 points
Nataliya [291]

Answer:

Volume of original toolbox = 180 in³

Yes, doubling one dimension only would double the volume of the toolbox.

Step-by-step explanation:

Volume = L x W x H

10 x 6 x 3 = 180 in³

proof:

double length = 20 x 6 x 3 = 360 in³, which is double the original

double width = 10 x 12 x 3 = 360 in³, which is double the original

double height = 10 x 6 x 6 = 360 in³, which is double the original
