Factor out the coefficient of the variable 1/2q plus 5/2

yes because there is exactly one y value for every x value

for function there can't be more than one value for every x value

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
