<h3>
Answer: x*a^2 or a^2*x</h3>
======================================
Work Shown:
a^(b+2) = a^b*a^2 ... break up the exponent
a^(b+2) = x*a^2 ... replace a^b with x
We don't know the value of 'a' nor the value of x, so we cannot evaluate further. This is the same as a^2*x because order of multiplication does not matter. For example, 2*3 = 6 and 3*2 = 6, so 2*3 = 3*2.
3x + 6y = 18 -6y
3x = 18 - 6y Divide by 3
3x/3=18/3-6y/3 Simplify
x=6-2y
Now we check by plugging in the value of x.
3(6-2y)+6y=18 simplify
18-6y+6y=18 simplify more
18=18.
NOW we know for sure that this is correct
x=6-2y
Let the number be x:
3*x-2=13
∴3x=13+2
∴3x=15 (divide both sides by 3)
∴x=5 the answer is C
9+4+7+3+10+9=42
42÷6= 34.5. I believe "mean" is the same as avgerage.
