George and 4 friends are building a two-story clubhouse using bricks. in six days they placed 905 bricks. if each person placed an equal number of bricks how many bricks did each person place?

There are 5 people total (George plus 4 friends). If they each placed an equal amount out of the 905 bricks placed, then we need to divide this number between the five. To do so, we divide 905 by 5.

905 / 5 = 181

They've each placed 181 bricks.

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! : )
