20 - 5 is her score after losing points:

15

Now, 15 + 10 is her score after her extra points.

25 points

Hope this helps!

First, let's subtract.
If Rita earned 20 points on the quiz, and then lost 5 for poor penmanship the equation will look like 20 - 5 = 15.
Then, if she earned 10 points for extra credit, we add 15 and 10 to get 25.

20 - 5 + 10 is what the equation should be.

correct Option is B i.e, 72x^2+288x^2-216x whose simplified form is: 360x^2-216x

Step-by-step explanation:

We need to solve the expression:

2[(6x)(6x)]+4[(12x - 9)(6x)]

Solving:

2[(6x)(6x)]+4[(12x - 9)(6x)]\\=2[36x^2]+4[(12x*6x)-(9*6x)]\\=72x^2+4[72x^2-54x]\\=72x^2+288x^2-216x\\=360x^2-216x

So, correct Option is B i.e, 72x^2+288x^2-216x whose simplified form is: 360x^2-216x
