1. Darius wants to simplify the expression below but does not have a calculator, (2/3)×(27/8) + 5
Which step should Darius take first to simplify the expression?
a.) Multiply the fractions
b. Multiply the first fraction by 5
C. Add 5 to the first fraction
d. Add 5 to the second fraction

Step-by-step explanation:

it's answer (a) because he has to multipy the fractions because always fractions goes first and then he needs to add 5

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! : )

it should be a.

hope it
