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.
Hoped this helped,

Use arithmetic sequence in order to get to answer:
a_n= a₁ rⁿ⁻¹
r is a common ratio, a₁ is the first term and a_n is the summation.
a_n= 1 (2/1)¹⁵⁻¹= 16384 pennies
Answer:
5.2
Step-by-step explanation:
distance(Mercury, Sun) = 5.8 x 10^7
distance(Venus, Sun) = 1.1 x 10^8
distance(Venus, Mars) = 1.1 x 10^8 - 5.8 x 10^7
The subtraction is a little easier if you borrow a power of 10 from the 10^8, multiplying 1.1 by 10.
simply subtract 5.8 from 11.0.
This gives us a result of 5.2 x 10^7.
X - y > 2 at (5, 4)
5 - 4 > 2
1 > 2
(5, 4) is not a solution to this inequality
