You would multiply 15 by 2 that would give you 30, therefore you multiply 45 by 2 which will be 90.

Answer:
27+4x+8y
or
4x+8y+27 ( I can reorder this a few different ways. I don't know what your choices are)
Step-by-step explanation:
11+4(x+2y+4)
We can apply distributive property to the 4(x+2y+4), this will give us 4x+8y+16.
Bring down the 11+ and we have 11+4x+8y+16.
The only like terms we have is 11 and 16. So reorder using commutative property and get 11+16+4x+8y.
I'm going to simplify the 11+16 part which gives us 27.
In the end we have 27+4x+8y.
Let me line up so it is all nice and neat:
11+4(x+2y+4)
11+4x+8y+16
11+16+4x+8y
27+4x+8y
Answer:
(1,5)
Step-by-step explanation:
The x coordinate of the midpoint is found by adding the x coordinates and dividing by 2
(6+-4)/2 = 2/2 =1
The y coordinate of the midpoint is found by adding the x coordinates and dividing by 2
( (8+2)/2 = 10/2 = 5
The mid point is (1,5)
54-15=39
if you want to check your answer you add 39+15=54
