Step-by-step explanation:
replace ab with x
If two triangles are similar, that means their side lengths are proportional, so we get the equation
![\frac{AB}{AC} =\frac{FG}{FH} \\\frac{x}{17} =\frac{16}{20} \\20x = 16 * 17\\x=13.6](https://tex.z-dn.net/?f=%5Cfrac%7BAB%7D%7BAC%7D%20%3D%5Cfrac%7BFG%7D%7BFH%7D%20%5C%5C%5Cfrac%7Bx%7D%7B17%7D%20%3D%5Cfrac%7B16%7D%7B20%7D%20%5C%5C20x%20%3D%2016%20%2A%2017%5C%5Cx%3D13.6)
Thus x = 13.6.

Answer:
Brand A: $0.05
Brand B: $0.07
Brand A is the better buy
Step-by-step explanation:

Brand B:
96x = 6.62
/96 /96
x = $0.07
Hope this helps!
3(2x + 4y - 2z) + 7(x + y - 4z) = 6x + 12y - 6z + 7x + 7y - 28z = 13x + 19y - 34z
Option c is the correct answer.
