Which missing piece of information would allow the triangles in the figure to be proven congruent by AAS? A) ∠A ≅ ∠A′

B) BC with a line on top ≅ BC with a line on top of it

C) ∠C ≅ ∠C′

D) AC with a line on top of it ≅ AC with a line on top of it

9514 1404 393

  C) ∠C ≅ ∠C′

Step-by-step explanation:

The figures show a marked angle and side. To use AAS, we need another angle that is not adjacent to the marked side. That angle is C (or C'), so we require ...

  ∠C ≅ ∠C′

r and t.

both are 64 degrees.

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! : )
