Simplify the following algebraic expression 2(x^2+3x)-10(x^2+2)

-8x^2+6x-20

Step-by-step explanation:

2(x^2+3x)-10(x^2+2)

2x^2+6x-10x^2-20

(2x^2-10x^2)+6x-20

-8x^2+6x-20

answer: 80,000

step-by-step explanation:

the population doubles every day.

10,000*2=20,000 day 4

20,000*2=40,000 day 5

40,000*2=80,000 day 6

one fourth of 9% = 2.25%

gavin is correct in saying : the equivalent quarterly interest rate would be

2.25%.
