Answer:

If the student worked 21 hours this month, she will earn $246.75.

Step-by-step explanation:

<em>Let </em>x<em> equal hours.</em>

If the student earns $11.75 per hour, we can represent this with the expression:

11.75x

If she worked 21 hours this month, then:

x=21

With that information, we can substitute 21 for x in the initial expression:

11.75(21)

Multiply:

246.75

Therefore, if the student worked 21 hours this month, she will earn $246.75.

-

We can check our work by setting the initial expression equal to our solution:

11.75x=246.75

Divide both sides of the equation by the coefficient of x, which is 11.75:

x=21

Since this quotient matches the number of hours she worked, our solution is correct!

Naya [18.7K]

Answer: Rico is right.

(-1)(3x + 5)²

Step-by-step explanation: If it were the difference of two squares, the -30x would not be there.

It makes sense to factor out (-1) fry the trinomial, leaving all positive terms.

Then factor 9x² + 30x + 25 as

(3x + 5)²
