Find the value of the lesser root of x2 - 7x + 12 = 0.
a) -3
b) -1
c) 1
d) 3

So then since we want the lesser root the correct answer on this case is:

D) 3

Step-by-step explanation:

For this case we have the followin expression:

For this case we can use the quadratic formula in order to solve it, given by:

And on this case a = 1, b = -7, c = 12. And if we replace we got:

So then since we want the lesser root the correct answer on this case is:

D) 3

step-by-step explanation:

the answer is 200

step-by-step explanation:

the way the question is worded, it seems to imply the $264 interest is simple interest, not compound interest.

the simple interest for 2 years is $264; the simple interest for 1 year is $132.

$132 interest on a $600 investment means an interest rate of (132/600)*100 = 22%.

the value of $200 at 22% interest compounded annually for three years is

200%281.22%29%5e3

the amount of interest is that value, minus the original $200.
