How do i do each problem, step by step? i am not good at geometry.

1) 10

2) 4.5

3) 28 ft

4) 240 in.

5) 8 in.

Step-by-step explanation:

For the first question, you know one of the pairs of sides, 6 and 9. This ratio stays the same, so 6/9=z/15 and z = 10.

For the 2nd question, do the same with the 8 and 6. 6/8=y/6, so y = 36/8 or 9/2 or 4.5.

For the 3rd question, call the longer side x. Then, 4/3 = x/21 and x = 28.

For the 4th question, it is scaled down by 3, so we need to scale the 80 in long up by 3, to make it 240 inches long.

Finally, for the last question, the maximum scale factor is 4, because of 12/3. Scale this the same way for the width and you get 2*4 = 8 in.

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! : )
