Erik collects miniature cars. He has one large case that has 20 cars. He also has 3 same size, smaller cases filled with cars. Let n = the number of cars in each smaller case. Write an expression we can use to determine the number of cars Erik has in all no matter how many each case holds. * Your answer

22

step-by-step explanation:

answer: 2x + 2 − 2 = 10 − 2; subtraction property of equality

step-by-step explanation:

the correct answer is 5 6 and 7

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.
