Which equation can be used to solve for xxx in the following diagram?

Choose 1

(Choice A)
A
60+ 90 + (4x - 20) = 18060+90+(4x−20)=18060, plus, 90, plus, left parenthesis, 4, x, minus, 20, right parenthesis, equals, 180

(Choice B)
B
60 + (4x - 20) = 9060+(4x−20)=9060, plus, left parenthesis, 4, x, minus, 20, right parenthesis, equals, 90

(Choice C)
C
60 + (4x - 20) = 18060+(4x−20)=

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

hope this

idk

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! : )
