Answer:
5x+8y
Step-by-step explanation:
We can first open the brackets by using the distrubitive propety.
2(x+4y)+3x
2x+8y+3x
Now we can combine like terms.
5x+8y.
I combined the 3x and the 2x. This works because imagined I have 3 of something then I got 2 more of that something I would now have 5 of that something.

you would move the decimal until you only have 1 number to the left of it and the rest on the right. we moved it three spots left in this case so your answer would be as follows.
1.8 x 10^3 is the answer

Cross multiply. Distribute...

OH GOD IT'S A QUADRATIC
<em>(our equation is in ax² + bx + c = 0 form. a=3. b= -38. c= -8.

Approximate values for x: -0.20714 or 12.874
Walmart: 10 pens/$8.99 -> $.89/pen
Walgreens: 25 pens/$19.75-> $.79
Walgreens has the better deal
6 times x (the variable) plus 14 so basically 6x+14
