Answer:
x=32
Step-by-step explanation:
x/2-7=9
1/2x-7=9
add seven to both sides
1/2x=16
multiple both sides by two
x=32
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>
Answer:
5:3
Step-by-step explanation:
to simplify this equation we have to find something that both numbers can be divided by
both numbers can be divided by 7
so when we divide the numbers we get
5b = 3c
so basically the ratio is 5:3
