Solve: x+4/4 = x/x-2 answers are {-4,2}

x=4                         x=-2

Step-by-step explanation:

x+4                  x

=

4                  x-2

Using cross products

(x+4)(x-2) = 4x

FOIL

x^2 -2x +4x -8 = 4x

Combine like terms

x^2 +2x -8 = 4x

Subtract 4x from each side

x^2 +2x-4x -8 = 4x-4x

x^2 -2x-8 =0

Factor

What 2 numbers multiply to -8 and add to -2

-4*2 =-8

-4+2 = -2

(x-4) (x+2) =0

Using the zero product property

x-4+4 =0+4         x+2-2=0-2

x=4                         x=-2

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

60

step-by-step explanation:

every triangle measures a total of 120 degrees. you have to find angle c. we know that isosceles triangles angles are equal. 60 degrees plus 60 degrees gives you 120.
