NEED HELP ASAP! 15 points! Benny earns $12.00 per hour as a lifeguard. He earns a bonus of $75.00 for taking a training course. Which graph best represents the number of hours must be worked to earn at least $399.00?

Step-by-step help:

399 - 75 = 324.

Now that we have the bonus out of the equation, the fraction is approximately

324/12.

Divide by 2,

162/6

Divide by 2 again,

81/3.

81 divided by 3 is 27.

So,

The answer is exactly 27.

Hope that helped!

I think maybe the first or second number line.

2/3

step-by-step explanation:

hello from mrbilldoesmath!

answer:

(7 x + 6 y) (49 x^2 - 42 x y + 36 y^2)

discussion:

the trick is to recognize that 343 = 7^3 and 216 = 6^3 and, in general,

a^3 + b^3 =   (a + b) (a^2 - a b + b^2).

in our case

343x^3+216y^3   =   (7x)^3 + (6y)^3

so take a = 7x and b = 6y in the above equation to get the answer.
