Use the x-intercept method to find all real solutions of the equation.
=9x^3-73x^2-96x+36=3x^3+x^2-3x+8

the answer is 13

step-by-step explanation:

5*5=25

12*12=144

25+144=169

169^2=13

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

step-by-step explanation:

the triangles are similar. therefore the corresponding sides are in proportion:

              cross multiply

            divide both sides by 32

you just switch the numbers basically so it would be 3/17
