Answer correctly for brainliest and also get a ! don't answer if you don't know it !

you would need to use the distance formula for this square root of (x2-x1)^2+(y2-y1)^2 

sqrt of (7-5)^2+(10-1)^2

sqrt of 2^2 + 9^2

sqrt of 4+81

sqrt of 85

9.2

assuming you mean addition: addition and subtraction are reverse operations.

step-by-step explanation:

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! : )
