Step-by-step explanation:

Whenever adding a positive to a negative, the answer will increase, it will be closer to zero and the positives than the original negative number.So, -10 + 30 = 30 - 1030 - 10 = 20

I hope this helps!

$f(x)=4x^2+6x\\\\g(x)=2x^2+13x+15\\\\(f\cdot g)(x)=(4x^2+6x)\cdot(2x^2+13x+15)=(4x^2)(2x^2)+(4x^2)(13x)+(4x^2)(15)+(6x)(2x^2)+(6x)(13x)+(6x)(15)\\\\=8x^4+52x^3+60x^2+12x^3+78x^2+90x=8x^4+64x^3+138x^2+90x$ $\left(\dfrac{f}{g}\right)(x)=\dfrac{4x^2+6x}{2x^2+13x+15}=\dfrac{2x(2x+3)}{2x^2+10x+3x+15}=\dfrac{2x(2x+3)}{2x(x+5)+3(x+5)}=\dfrac{2x(2x+3)}{(x+5)(2x+3)}=\dfrac{2x}{x+5}$
