Asquare with an area a^2 of is enlarged to a square with an area of 25a^2. how was the side of the smaller square changed?
a. the side length was increased by 5.
b. the side length was multiplied by 5.
c. the side length was increased by 10.
d. the side length was multiplied by 10.

a square with an area of a² is enlarged to a square with an area of 25a².

The side length of the smaller square was changed when The side length was multiplied by 5.

Area = (1a)² = a²

Area = 1a * 5 = 5a ⇒ (5a)² = 25a²

So, your answer would be B. The side length was multiplied by 5

step-by-step explanation:

there are 70 more legs than eyes at the dog show (196 – 126 = 70). dogs have two more legs than eyes, and humans have the same number of legs as eyes. thus 70 is twice the number of dogs at the show, so the number of dogs is half of 70, which is 35. to get the number of humans, subtract 35 from 63: 63 – 35 = 28.
