2/3 / 8/7 flip the second fraction and multiply straight across
2/3 x 7/8 2 x 7 = 14
3 x 8 = 24 so you have 14/24 if you need to simplify, since both numerator and denominator are even so divide by 2. Which gives you 7/12
Hope this helps you :)
Answer:
Length: 23.38
Width: 3.34
Step-by-step explanation:
First I drew out a diagram so that I could visibly see the problem. [ a rectangle with 7x on one side and x on the other.
So to find the area you multiply length time width and 7x times x is 7x^2. The actual area is given: 78, so you set that equal to 7x^2.
Then you want to divide by 7 to get 11.14. Then you want to take the square root of 11.14 to get 3.338 which rounds to 3.34 {try not to round until the very end]. This gives you the width of the rectangle, so to find the length you would have to multiply x by 7 to get 23.38. When you multiply the length and width (3.34 x 23.38) you get 78.08 which can round to 78.
7x^2 = 78
x^2 = 78/7
x^2= 11.142...
x = sqrt(1.142...)
x = 3.338 --> 3.34 --> width
3.34 x 7 --> 23.38 --> length
3.34 x 23.38 --> 70.8
Answer:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
Step-by-step explanation:
There are four methods of solving quadratic equation:
1. Factorization method
2. Formula method
3. Completing the square method
4. Graphical method
1. Factorization method: Use factorization method when the quadratic equation can easily be factorize.
Example: x^2 - 4x - 12 = 0
(x-2)(x+6)
2. Formula method: This can be used when factoring the quadratic equation looks difficult or you are given instruction to use formula method
3. Completing the square method: Use completing the square method when you are instructed to do so.
4. Graphical method: This method is used when instructed to find x intercept.
By PEMDAS (or any alternative), <em>the first step should be to divide</em>, as D comes before A. So, 16 ÷ 4.
The number is -3 because -3 minus 16 equals -19.
