Help and explain cause i’m dumb :)

$25.25

Step-by-step explanation:

Since one bone costs $2.95 each and Mrs. Lawrence bought 5 you are going to multiply $2.95 * 5 and get $14.75. Then since one bag of treats costs $10.50 you are going to add $14.75 + $10.50 to get a total of $25.25

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.
