The factorization below is missing two positive integers a and b. 6x^(3)+18x^(2)-240x=6x(x-a)(x+b) Factor the polynomial and the

Dvinal [7]

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.

Quadrilateral ABCD is inscribed in a circle. What’s the measure of angle B

wariber [46]

Well the equation is 6x + x + 19 = 180 or 7x + 19 = 180. You subtract 19 from 180 to get 161. Then you divide 161 by 7 to get x = 23. Finally, you plug x in to get 6(23) + 19 or 157°
