Simplify.
y = (x + 1)2 -

Step-by-step explanation:

Assuming it is supposed to be y = 2- (x+1)

y= x-1

or if it is supposed to be y = -2(x+1)

y= -2x-2

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
