If I had a yard that was 100 feet by 100 feet, and a house in the middle of it that was 20 feet by 20 feet, what is the area of the yard, not including the house?

C. 10000-400 = 9600 square feet

Step-by-step explanation:

The area of a square is s^2, so the area of the yard is 100^2=10000. The area of the house is 20^2=400. Since we do not include the area of the house, 10000-400=9600 square feet.

(1, –1), (16, –4), (36, –6)

step-by-step explanation:

given that the function is

this can also be written as

we have to graph this function and check which list of points lie on the graph

see attachment for graph:

we find that the points lying are (1,-1) (16,-4) and (36,-6)

since square root is there we find that x can only be posiitve but y can be since square root both positive and negative.
