The term perfect square means that the square root of the number is a whole number.
Distributive property. look. 15f-40g+2g then -40+2 is -38 so 15f-38 is your answer
For this case we have the following equations:

The break even point occur when C = R:
We have then:

Clearing x we have:

Then, substituting in any of the equations we have:

The break even point is:
(4, 176)
Answer:
The break even point is:
(4, 176)
Answer:about 2 1/4 weeks
Step-by-step explanation:
6 consecutive even numbers
First x
Second x+2
Third x+4
Fourth x+6
Fifth x+8
Sixth x+10
126=x+x+2+x+4+x+6+x+8+x+10
126=6x+30
Subtract 30 from both sides
96=6x
Divide both sides by 6
x=16
Fourth x+6=16+6=22
