Jennifer has a square bedroom. the area of her room is 144 ft2. what is the length of one side of jennifer’s room?
a) 10 ft
b) 12 ft
c) 18 ft
d) 36 ft

Option B.

Step-by-step explanation:

we know that

The area of a square is equal to

where

x is the length side of the square

In this problem we have

substitute and solve for x

suqre root both sides

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)

let m = monomial

let t = trinomial

so, m times t = t.

monomial times a trinomial = another trinomial.
