I think z because if you flip the shape around it will create the same shape as z
A number times 1 always equals itself, so: 4×1 = 4, OR 2×2 = 4
B. Sandwich costs $7.70 and the soda costs $2.20
(1.75 + 2 x 0.25 + 5 x 0.05) x 24= 17
When multiplying by 4, you can simply multiply it by 2 twice (prime factorization).
In this example-
4 times 8 = 32
2 times 2 times 8 = 32
Hope this helped!
