Alana's house sits on a rectangular lot with dimensions 62.4 feet by 108.6 feet. use mental math to find the perimeter

62.4 + 108.6 = 171

171*2=(170+1)*2=340+2=342

 Perimeter = 342 feet

 The perimeter of a figure is defined by length of its 2D shape.

 For a rectangle it is the sum of the length of all its sides

 P = a1 + a2 +b1 + b2

Since a rectangle has two sides with the same lengths as the other two

a1 = a2 ; b1 = b2

 P = 2(a1 + b2) 

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)
