a rectangular field is X to the second power - 150 x + 5400 the width in feet is x - 60 what is the length in feet

x - 90

Step-by-step explanation:

The area of a rectangle is length times width. If the width is x - 60, then the length times x - 60 equals x^2-150x+5400. Let the length be l. Then:

First, we must factor the right hand side of the equation. We need two numbers that multiply to 5400 and sum to -150. Because two numbers that are negative multiplied together equals a positive number, we can just have two negative numbers that multiply to 5400 and sum to -150. Because -150 is so far from 5400, the multiples must be close to each other. We see that 60 times 90 are the closest multiples, and that 60+90 = 150.

We can factor this as (x - 60)(x-90):

Dividing both sides by (x - 60), we have:

false

step-by-step explanation:

rulers and compasses arent required in order to bisect an angle because when bisecting angles, you're making a "half circle" and considering in order to bisect an angle it wouldn't be straight, you wouldn't need either of the two

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! : )
