Answer:
6 is a factor of n
Step-by-step explanation:
2 is a factor of n and 3 is a factor of n means
n = 2×3×k
= 6×k
then n = 6×k
then 6 is a factor of n
1. Use the FOIL (first, outside, inside, last) method:
F: x*x=x^2
O: x*-2=-2x
I: 3*x=3x
L: 3*-2=-6
x^2-2x+3x-6
<em>*Combine like terms*</em>
x^2+x-6
2. Look for the greatest common factor (GCF) of 15 and 5. It is 5 (15/5=3 and 5/5=1)
5(3x+1)
3. You want to find two numbers whose product is 6 and whose sum is -5. -3 and -2 complete these requirements.
(x-3)(x-2)
4. Solve for x:
<em>*Add x to both sides*</em>
y+x=ab
<em>*Subtract y from both sides*</em>
x=ab-y
8. Plug in 0.5 for x and solve:
10-8(0.5)
10-4
6
10. <em>*Multiply both sides by 5*</em>
2x-3=20
<em>*Add 3 to both sides*</em>
2x=23
<em>*Divide both sides by 2*</em>
x=23/2
I did what I could. Hope I could help!!

Answer: FIRST OPTION
Step-by-step explanation:
According the quotient of powers property, when you have the division of two powers with the same base, then you must subtract the exponents.
Therefore, keeping the property above on mind, you have that the quotient is the shown below:
