Which expression is equivalent to

(x^2 + 2x + 3) (x-4)?

x^3−2x^2−5x−12

Step-by-step explanation:

(x2+2x+3)(x−4)

= (x^2+2x+3)(x+−4)

=(x^2)(x)+(x^2)(−4)+(2x)(x)+(2x)(−4)+(3)(x)+(3)(−4)

=x^3−4x^2+2x^2−8x+3x−12

=x^3−2x^2−5x−12

Does that help? Tell me if it doesn't!

answer: since the question is talking about growth you have to use the growth formula which is inital amount (1 + growth)^time

step-by-step explanation:

the intial amount is 1200, the growth is 4.8, and the time is 7. plug those numbers into the equation, also i think you have to change 4.8 into a percent. but, i have forgotton how to do that. if this is a online class go on to the lesson.
