Answer:

12

Step-by-step explanation:

Alr so correct me if I'm wrong but I think you made a mistake. It says find 44 of those rectangles. You found just 1 in that case which the area is 3/11. You have to do 3/11 X 44 which is

3/11 x 44/1 = 132/11 = 12.

|x+18|=1
zepelin [54]
The absolute value, or modulus, of a number is its distance from zero, or essentially its magnitude.

The absolute value produces a positive answer.

We have this definition for the absolute value, taking into account its different values for different signs:

|x|= \left \{ {{x, \ \ \ x \ \geq \ 0} \atop {-x, \ \ \ x \ \ \textless \  \ 0}} \right.

Thus, for |x+18|=1, we split the absolute value as such:

x+18=1 and x+18=-1

We solve each case.

x=-17 and x=-19

We check these solutions.

|-17+18|=1\\|1|=1\\1=1
and
|-19+18|=1\\|-1|=1\\1=1
