Can someone please help?

11. last option with x ≠ 1 is the choice

Step-by-step explanation:

x² + 5x +6 = (x + 2) (x + 3)

x² + x - 12 = (x - 3) (x + 4)

x² + x - 2 = (x - 1) (x + 2)

(x² + 5x +6) / (x + 4) * (x² + x - 12) / (x² + x - 2)

(x + 2) (x + 3) / (x + 4) * (x - 3) (x + 4) / (x - 1) (x + 2)

= (x + 3) ( x - 3) / (x - 1)

x - 1 ≠ 0  If the denominator of a fraction is zero, the expression is not a legal fraction because it's overall value will be undefined

I think only the last option that has x ≠ 1 is the answer

answer: i wpould go with c

step-by-step explanation:

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
