Mariah is setting tile on the floors of her rectangular kitchen and square breakfast area. the diagram shows the dimensions of the 2 rooms. each tile covers 1 square foot. if each tile cost $1.29, how much will mariah pay to buy tile for both rooms?

at first,

area of breakfast area,

area of kitchen,

now, total area,

rate per square ft = $ 1.29

total cost ,

= $ 309.60

answer is B.

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! : )
