Answer:

x = - 8, x = 6

Step-by-step explanation:

${x}^{2} + 2x - 48 = 0 \\ \\ {x}^{2} + 8x - 6x - 48 = 0 \\ \\ x(x + 8) - 6(x + 8) = 0 \\ \\ (x + 8)(x - 6) = 0 \\ \\ x + 8 = 0 \: \: or \: \: x - 6 = 0 \\ \\ x = - 8, \: \: \: \: x = 6 \\$

What is the sum of these mixed numbers 4 2/3+ 3 1/9

Mariana [72]

Hello!

First you have to make the denominators the same so the numbers are comparable.

You can multiply the top and bottom number in 2/3 to get 6/9

Now you add

4 6/9 + 3 1/9 = 7 7/9

The answer is 7 7/9

Hope this helps!
