So here's what we have so far:
2 mm: 8 m
We can factor out a 2:
1 mm: 4 m
If you want, we can go further by converting into the same unit. A little unorthodox, but just to show how to do it:
1 meter = 1000 millimeters
4 * 1000 = 4000
1 mm: 4000 mm
All of them except for the first one are differences of squares. Differences of squares is a form of factoring perfect squares. A 'perfect square' is just a fancy term that basically means you are doubling a number. Like the number 25 you multiply 5x5 to get that number and if you were to take the square root of that number you would also get 5. For it to be differences of two squares you have to have two numbers that if square rooted (in a calculater if you need one) would turn out to be a whole number or 'perfect'.
Answer:
6+2(n+4) = (3-n)÷2
Step-by-step explanation:
6 + 2n + 8 = (3-n)/2
14 + 2n = (3-n)/2
multiply through by 2 to eliminate the denominator
28 + 4n = 3 - n
25 + 4n = -n
25 = -5n
n = -5
Answer:
The answer to your question is: 2 pieces of paper.
Step-by-step explanation:
Data
6 ft²
1 present = 3 1/8 ft²
Process
Get the result of adding the area needed to wrap to presents.
3 1/8 + 3 1/8 = 6 2/8 = 6 1/4 Remember to add the
whole numbers and the
fractions independently.
Each paper measures 6 ft² and we need to wrap two presents 6 1/4 ft², so we need to pieces of paper to wrap the presents.
