Answer:

a = 5

Step-by-step explanation:

Hello, please consider the following.

$6x^3+18x^2-240x=6x(x^2+3x-40)\\\\\text{** The sum of the zeroes is -3=-8+5 and the product is -40=-8*5. **}\\\\\text{** So, we can factorise. **}\\\\6x^3+18x^2-240x=6x(x^2+3x-40)=6x(x^2+8x-5x-40)\\\\=6x(x(x+8)-5(x+8))\\\\\large \boxed{=6x(x+8)(x-5)}$

So, a = 5.

Thank you.

Lisa was assigned 48 pages to read for English class. She has finished ¾ of the assignment. How many more pages must she read?

12 pages

Step-by-step explanation:

If you divide 48 by four, you get twelve. 3/4 of 48 is 36, so you subtract the 36 from the 48 and get 12.
