================================================
Explanation:
These are the steps to focus on
step 3: -6x - 8 < -2
step 4: -6x < 6
The move from the third step to the fourth step has us adding 8 to both sides. Therefore, we use the addition property of inequality.
That property has four forms
- If
then
- If
then
- If
then
- If
then
It's similar to the idea of starting with a = b, then adding c to both sides to get a+c = b+c
We add the same thing to both sides to keep things balanced.
Answer:
Step-by-step explanation:
A(3,-2) ; B(6,-2)
AB = 3 units
B(6,-2) ; C(6,5)
BC = 7 units
Area of rectangle = length * width
= AB * BC
= 3 * 7
= 21 square units
