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)

Yes 1.999 is an <span>irrational number</span>
A ray is a defined term because it has no width or depth is described using an undefined term has an informal definition travels forever in one way
Answer:
x = 2
Table:
0,0
3,9
-2,-6
4,12
Step-by-step explanation:
distribute
3(2x+1)=15
6x+3 = 15
subtract 3 from both sides
6x + 3 = 15
6x + 3 - 3 = 15 - 3
simplify
6x= 12
divide both sides by 6
answer= x=2
