Answer: 
Step-by-step explanation:
You need to remember:
1. The Product of powers property: 
2. The Power of a power property: 
In this case, given:

You need to follow these steps in order to simplify it:
1. Apply the Product of powers property:

2. Apply the Power of a power property:

3. Finally, since
and
, you get:

N + 9 = 12 means N is a number which, when added to 9, must give the answer 12. So N can only be the number 3 because only 3 + 9 is equal to 12.
9) (-12) – 3 5-15. 10) (-2) – 5. = -7. 11) (-9)–1 = -10. 12) 3-1. = 2. 13) 10- (-3) = 13 ... n-4 = 22. 9) the product of c and 10 is 24. 10) the sum of a number and 7 is 44 ... 17) (-5)-(-9) . ” (+8)+6-7. 18 (-26) – (-5) -7. 18) (-3). (-1). 24. 19) ī. ” (-2). 3 -2. -3.
Answer:
D) 86 – 18x – 8 = 12x + 18
X = 2
Step-by-step explanation:
86 – 2 (9x + 4) = 12x + 18
This question has a straight forward answer...
It's just to open up the bracket and ensure that the negative sign before the bracket multiply the values in the bracket exactly.
So opening up the bracket gives us this as the answer
86 - 18x -8 = 12x +18
86-18-8 = 12x+ 18x
60 = 30x
X = 2
The answer is c. Hope that helps :)
