The Millers are getting new carpet in their basement. How many total square feet of carpet will they need to buy?

125 feet

step by step explanation:

i dont know how to explain it but you have to draw a line in the box where the shape is creating a small other rectangle if that makes sense. so it breaks it into 2 shapes, one that is 9 by 10 and one that is 5 by 7 because 16 - 9 is 7. its sounds confusing but 125 is the answer

x=-2

infinite number of lines, so there is an infinite number of equations.

step-by-step explanation:

there are an infinite number of line that passes through the point (-2,5)

x=-2   is one line that passes through the point

y = 5 is another line that passes through the point

(these two lines are perpendicular to each other).

since the number of   numbers are infinite and the slope is the ratio of two numbers,(change in y over change in x) we can have an infinite number of slopes.     our only condition is that it passes through the point (-2,5)
