David’s watch broke. He decides to get it fixed instead of replacing it. The total cost to repair the watch can be represented b
y 0.07(45h) + 45h, where h represents the number of hours it takes to repair the watch. What part of the expression represents the amount of tax David has to pay? Explain.
45h represents how much it costs per hour to get it fixed and how long it takes to get it fixed 0.07(45h) would represent the tax because it is 7% of the cost pretax
A triangle ABC is similar to a triangle A´B´C´ The scale factor of the dilatation : s. 0 * s =0 4 * s = 10 6 * s = 15 s= 10/4=15/6=2.5 The scale factor of the dilatation is 2.5. It is shown in the attachment.
