How do you solve this? [question in attachment]

In order to find the perimeter of a shape, we should add all of its sides.
Since a triangle has only 3 sides, we add 3 sides together, like so:-
⇒ 9x-7+12x-13+3x+8
Combine like terms:-
➪ 9x+12x+3x-7-13-8
Which simplifies to
➪9x+15x-7-21
On further simplification,
➪24x-28
So we conclude that the perimeter of the triangle is 24x-28 units.

Answer:
You would have $343.37 at the end of the 2 years.
Step-by-step explanation:
Interest earned is like bonus money the bank pays you just for keeping money

P: the starting balance of the account (also called initial deposit, or principal)
A: the new balance in the account after N years.
t: the number of years or time
r: the interest rate, (in decimal form)
n: the number of times the interest is compounded each year.
Annually = each year = 1
P =$300, r = 7%, t = 2, n = 1, A = ?
Substitute the numbers into the "Compound Interest Formula".











So you would have $343.37 at the end of the 2 years.
Look at the chart

False.
The volume of a cylinder is how much space it takes up INSIDE. You would use volume to measure how much you can put something inside (like water)
Surface area measures the OUTSIDE of a shape. In this case, you'd use surface area to determine how much paper he needs.

<span>With a boys to girls ratio of 8:7, this means 8/15 of the campers are boys and 7/15 of the campers are girls.
We are told that there are 195 total campers.
To find # of boys: 195 (the total # of campers) x 8/15 (fraction of the campers that are boys) = 104 boys
To find # of girls: 195 (total # of campers) x 7/15 (fraction of the campers that are girls) = 91 girls
Note: If you do not know how to multiply by fractions, let me know, I have another trick that takes more time but doesn't require the use of fractions.
