What is the difference of the polynomials? (5x^3+4x^2)- (6x^2-2x-9)
-x^3+6x^2+9
-x^3+2x^2-9
5x^3-2x^2-2x-9
5x^3-2x^2+2x+9

7 weeks

step-by-step explanation:

convert each fraction to the least common multiple of 20, so 3/4 = 15/20 & 1/10 = 2/20, then divide 15 by 2 and you get a little over 7, so the food will last 7 weeks.

for this pair of functions g(x)=x-2 and f(x)=|x| is (g o f)(a)= |a| -2

step-by-step explanation:

g(x)=x-2

f(x)=|x|

(g o f)(a)=?

(g o f)(x)=g(f(x))

(g o f)(x)=g(|x|)

(g o f)(x)=|x|-2

(g o f)(a)=|a|-2

what shape is

60: 45 =12: 9 =4: 3 so the answer is 4: 3
