Answer:
3(4+n) = 12+n is an equation that could be used.
12n = 12+n
11n = 12
n= 1+1/11
Step-by-step explanation:
Step 2 subtract
Step 4 multiple
Answer:B
Step-by-step explanation:
A B C D E F G and L are proportional
and H I J and K are non-proportional.
Note that (a+b)^2 = a^2 + 2ab + b^2.
Therefore,
b^x (b^x )^2
<span>(2a^x +1/2 b^x)^2 becomes (2a^x)^2 + 2(2a^x)(-------- ) + ------------
2 4
LCD is 4. Thus, we have
4 [ (2a^(2x) ] + 8</span>a^x*b^x + b^(2x)
<span> </span>
