Solve x^3+2x^2-5x-6=0 given that 2 is a zero of f(x)= x^3+2x^2-5x-6

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

step-by-step explanation:

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870

answer: no

step-by-step explanation: because the big angle will spread away the 2 side that it is on and make the opposite side even longer.
