How do i find the total surface area of i'm dumb; (

114.92 in²

Step-by-step explanation:

There are 5 faces: three rectangles and two triangles.

The area of the base rectangle is 5 × 9.4 = 47.

The area of the larger rectangle on top is 5 × 7.2 = 36.

The area of the smaller rectangle on top is 5 × 3 = 15.

The area of each triangle is ½ × 9.4 × 1.8 = 8.46.

The total area is:

47 + 36 + 15 + 8.46 + 8.46 = 114.92.

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! : )
