For this case we have:

Let

a = -2

If we want the result of the product a * a, we have:

a * a = (- 2) (- 2)

The law of multiplication of signs states that:

- * - = +

- * + = -

+ * - = -

+ * + = +

Also,2 * 2 = 4

So, we have to evaluate a = -2, the product a * a is given by:

a * a = + 4

Answer:

Option 2

E is the midpoint of AB. If<br> AE = 4x +6 and EB = 10x - 12,<br> what is AB?
zzz [600]

Answer:

36

Step-by-step explanation:

Since E is the midpoint, AE and EB are equal. We can write this as such,

4x+6=10x-12 if we solve from here we get 6x=18. Simplify to get x=3. sub in three for  x in the AE equation, 4(3)+6 and solve. You'd get 18 as your answer. Double that to get the solution since AE= 1/2AB. 18*2= 36

AB=36
