Now we use FOIL to rewrite the expression.
FOIL is:
First
Outer
Inner
Last
That's the order we will be distributing the variables in the parentheses.

Combine like terms:

That's your final answer.
Hope that helps.
Since the angles sum of △ is 180°,here's the equation:
60°+65°+(8x+7)=180°
8x+7=180°-60°-65°
8x=55-7
x=48/8
x=6
Thus,the answer is x=6

Answer:
5y +3
Step-by-step explanation:
3(y + 1) + 2y =
3y +3 +2y =
5y +3
Answer:

Step-by-step explanation:
We are given the following information in the question.
The open interval: (- 18,22).
Let p belong to the given interval then p represents all the values belonging to the given interval.
Open Interval: An open interval is a interval that does not include the end points.
Thus, we can write:

is the required inequality form required.
That is p can take values greater than -18 and smaller than 22.
