42

(x+1)

(x-1)

(x+2)

(x-2)

(x+3)

(x-3)

(x+4)

(x-4)

The factors are

Step-by-step explanation:

we have

equate the expression to zero

Group terms that contain the same variable, and move the constant to the opposite side of the equation

Factor the leading coefficient

Complete the square. Remember to balance the equation by adding the same constants to each side

Rewrite as perfect squares

Take square root both sides

therefore

i think the amount would be $140.62

answer: the angel abc is 30°,and the abc is a triangle where the angel bac is 90°

so ac is the half of 24=12ft,and from the pythagorean theorem we find ba

ba=√bc^2-ac^2=√576-144=√432=12√3ft

so bac is 12+12√3=12(1+√3)ft
