Which of the following describes the correct process for solving the equation 2x − 4 = 20 and arrives at the correct solution?

add 4 to both sides, and then divide by 2. the solution is x = 12.
divide both sides by −4, and then subtract 2. the solution is x = −7.
subtract 4 from both sides, and then divide by 2. the solution is x = −12.
multiply both sides by −4, and then divide by 2. the solution is x = −40.

i pretty sure it is

answer: b. f(x) = (x + 2)^3 (x^2 - 7x + 3)^4

step-by-step explanation:

polynomials always have as many roots as their order. this is a 4th order polynomial- hence 4 roots!

complex roots of polynomials always come in pairs. the quadratic equation has the "+/-" in that will alwaysgenerate m+ni amd m-ni, so 7-2i must be a root of this polynomial equation.

the order of the numerator and denominator are both 2. so the horizontal asymptote is y=a2/b2 =7

verticle asymptotes are the forbidden x-values. f(x) becomes undefined at x=-3 because this value will cause a zero denominator.

a graph of r(x) will have vertical asymptotes at ±1 because these values will make the denominator zero. so the domain of the function cannot include ±1.

you 're wlecome! : )

step-by-step explanation:

i = prt

i = 1,5000 * 0.025 * 2

i = 75
