Question

I really don’t get it pls help me The choices are 3.1 10.4 13.8 13.0

Answer 1

x+2           (x+2) + 8

-------  =    ---------------

14                14+9

solve by using cross products

(x+2) * (14+9) = 14*(x+2+8)

(x+2)*23 = 14*(x+10)

distribute

23x+46 = 14x+140

subtract 14x from each side

9x+46 = 140

subtract 46 from each side

9x =94

x = 94/4

x = 10 4/9 cm
