The tax rate as a percent, r, charged on an item can be determined using the formula - 1 = r, where c is the final
cost of the item and p is the price of the item before tax. louise rewrites the equation to solve for the final cost of the
item: c = p(1 + r). what is the final cost of a $40 item after an 8% tax is applied?

just do 5.2 + 2 ( 7.2) and 1/3 x 3 (.9) and youv'e got your equation. 0.9( 9/10) + 7.2 ^2 = 16.4 hope i could !

step-by-step explanation:

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
