rich borrowed 100,000 for a period of five years. his interest rate is 3%. how much interest will rich pay in all?

15000  ( I THINK)

Step-by-step explanation:

you have to mutiply 100000 times 5 times 3% and you get 100000.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13
