Which expression is equivalent to 3 x + 2 + 5 x − 4 ?

8x - 2

Step-by-step explanation:

well i solved it by doing 3x +5x to get 8x then subtract -4 +2 to get -2

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

(picture explains)

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
