Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30

Hi!
To find the range of possible values of x, we have to side 1 from side 2...
7.1 - 5.6 = 1.5
The smallest side x could be is 1.5.
Now add side 1 to side 2
7.1 + 5.6 = 12.7
The biggest side x could be is 12.7
So x could be anywhere from 1.5 to 12.7 (or, 1.5 < x < 12.7)
Hope this helps! :)

<h3>How many teams can she make?</h3>
Division is the process of putting a number into equal groups using another number. The sign used to denote division is ÷. Division is one of the basic mathematical operations. Other basic mathematical operations include addition, subtraction, multiplication.
The number of teams that can be made can be determined by dividing the total number of friends by the total number of players in each team. The whole number that is derived from the division process is the number of teams teams that can be made given the total number of friends and the number of people that have to be in each group.
Number of teams she can make = total number of friends / number of people in each group
31 / 3 = 10 remainder 1
So, only 10 teams can be made. one person would not be on any team.
