Answer:
2x + 12
Step-by-step explanation:
Example of Associative Property Addition:
a + (b+c) = b + (a+c)
Now, implement it to the given expression:
(2x+8) + 4 = 2x + (8+4)
That simplifies to:
2x + 12
The y-intercept is the value of y when the graph intersects the y-axis. Graphs intersect the y-axis when x=0, so we just substitute in x=0 to get:
y=2(0+3)(0+4)
y=2(3)(4)
y=24
Therefore, 24 is our answer.

Answer:
534.07?
Step-by-step explanation:
A number greater than or equal to 1 but less than 10 is the definition of scientific notation.
The only number on the list that does not fit the definition above is 11•10^21.
Do you see why?
11•10^21 > 1 but not less than 10.
Understand?
