<span>This is just one example of how you can see the geometry figures in everyday life: say you want to plan how to arrange your furniture. You take a pen and paper and you can use geometric figures to plan how to best arrange the furniture in your room. Also, you can use geometric figures to see if your objects will fit onto shelves and generally to plan the interior - the problem at hand is planning your house and the geometric figures can help you plan!</span>
There's a lot of ways to solve this and get the same answer. No matter what, you definitely need to convert feet an yards.
Starting with what you know, one balloon needs 2.5 feet of ribbon.
You also know that three feet make a yard.
Your final answer asks for yards of ribbon for 18 balloons.
So, some ways to solve would be:
1. Multiply 2.5 by 18. That would end up being 45 feet for 18 balloons. You want yards. Yards are bigger than feet, and so you would want to divide. 45 divided by 3 is 15 yards for 18 balloons.
You could also do:
2. Convert first. 2.5 feet would be not a whole number of yards, but you would do 2.5 divided by 3. It would be a decimal ( you could find out in a calculator ) then, multiply by 18 for the number of balloons and you get 15 yards for 18 balloons.
The answer would ultimately be 15.
Answer:
Step-by-step explanation:
r² - 12r - 28 = 0
r² - (14 - 2)r - 28 = 0
r² - 14r + 2r - 28 = 0
r ( r - 14 ) + 2 ( r - 14 ) = 0
( r - 14) ( r + 2 ) = 0
Either
r - 14 = 0
r = 14
or
r + 2 = 0
r = -2
therefore r = - 2 or 14
