One week 72% of the animals I came to the veterinary Hospital were dogs if they were 230 in total how many were dogs

166

Step-by-step explanation:

230*.72=165.6. Round up to 166 because you can't have part of a dog. (At least you shouldn't...)

2 equivalent expressions to represent the area of a rectangle and the top is n-3 and the side is 2

area of the rectangle = length * width

given length = n - 3

width = 2

replace it in the area

so area of the rectangle = (n-3) *2

= 2(n-3)

one of the expression is 2(n-3)

to get another expression we distribute 2 inside the parenthesis

2(n-3) is 2n - 6

so another expression is 2n - 6

two equivalent expression are

2(n - 3)   , 2n - 6
