Answer:
Step-by-step explanation:
You can only add radicals if the value inside the square root symbol is the exact same, therefore, this one is 6. To find the sum, we can add the values outside the square root symbol (3 and 4) to get our new radical.
We can also check this.
≈ 7.35
≈ 9.8
≈ 17.15
7.35+9.8 = 17.15
Hope this helped!
We can use a variable equation to solve this. Let A represent alan's age, B represent bob's age, and C represent Cindy's age. So Bob's age would be Alan's age - 5, or a -5 = B. Then Bob's age would be double Cindy's age, so that means 2 multiplied by Cindy's age = Bob's age, or 2C = B. Your two equations are:
A - 5 = B
2C = B
Also a third equation that helps is A + B + C = 20.
Finally, here are the ages.
Alan = 11 years old
Bob = 6 years old
Cindy = 3 years old.

Answer:
6(x-6)+4=-32+62
6x -36 + 4 = -32 + 62
6x -32 = 30
6x -32 + 32 = 30 -32
6x = -2
6/6x = -2/6
x = -.333
Step-by-step explanation:
6(x-6)+4=-32+62
6x -36 + 4 = -32 + 62
6x -32 = 30
6x -32 + 32 = 30 -32
6x = -2
6/6x = -2/6
x = -.333
