Answer:
3 3/5 gallons per hour
Step-by-step explanation:
3/5 times 6 equals 18/5
18/5=3 3/5
Angle W and Y are right angles and equal to 90 degrees each. Angle z and angle x are same side interior angles and they have a sum of 180 degrees because of the same side interior angles postulate.
so W= 90 Y=90 X+Z= 180 . so 90+180+90 =360 degrees. B.
Answer:

Step-by-step explanation:
1) Rewrite
in the form
, where a = y and b = 1.

2) Use Square of Difference:
.

3) Factor
.
1 - Ask: Which two numbers add up to 6 and multiply to -7?
-1 and 7
2 - Rewrite the expression using the above.

Outcome/Result: 
4) Rewrite the expression with a common denominator.

5) Expand.

6) Collect like terms.

7) Simplify
to 

So, we have x=√8x. The square root is a number times itself, so x=√x*x. That means that 8 is x.
