First, you have to set up an equation using the formula for area of a rectangle:
L x W = H. Then, plug in what you know: 8 x W = 56. Then, solve for x by dividing 56 by 8: W=7.
Answer:
5 carnations in each arrangement
Total of 60 carnations used
Step-by-step explanation:
First calculate how many flowers are in each arrangement by dividing the total number of flowers by the number of arrangements:
96 ÷ 12 = 8
Given each arrangement has 3 roses, subtract 3 from 8 to find the number of carnations in each arrangement:
8 - 3 = 5
Therefore, there are 5 carnations in each arrangement
Total number of carnations used = 5 x 12 = 60
The one on the left is -5/6
The one on the right is 1/21
The least common denominator would be 2x^2
that is because you would have to multiply the first fraction by 2x
but you can't just somehow simplify 2x^2, it wouldn't be right
4/x * -4/2x^2
2x*4/(2x*x) * -4/2x^2
8x /2x^2 * -4/2x^2
Then you would complete it
Hope this helps :)
