Answer:
x^2 + 5n = 4mx
=> x^2 - 4mx + 5n = 0
D=0 (since one root then roots are equal)
b^2-4ac = 0
(-4m)^2 - 4(1)(5n) = 0
16m^2 - 20n = 0
16m^2 = 20n
8m^2 = 10n
4m^2 = 5n
hope it helps.......
Order of operations are:
<span>1. Parentheses (simplify inside 'em)
2. Exponents
3. Multiplication and Division (from left to right)
<span>4. Addition and Subtraction (from left to right)
So, on your first one:
Parentheses first:8(3+4)-2*8/(5-3)
8(7)-2*8/(2)
There are no exponents so multiplication and division:56-16/2
56-8
Finally, addition and subtraction:56-8=48
Your second problem is a bit more complicated but follows the same rules:
</span></span>

<span><span>
Parentheses first:</span></span>

<span><span>
Now, exponents. Even though they are inside parentheses, we can't go further until we simply those.
(64+81)/5
Now back to parentheses:(145)/5
Division:
145/5=29

Answer:
The total golf balls Jack has now in terms of expression is as below

Where a is total number of balls and b is number of balls in each bag.
Step-by-step explanation:
Solution:
let a be the total number of balls and b is the number of balls in each bag.
Number of bags is 3.
So total number of balls before the friend gave is 
Now the friend has given him 6 more golf balls then the total number of balls will become 3b + 6.
Therefore, the required expression is

The answer is 150 oz of solution a and 30oz of solution b. I’m adding in the work please ask if you have any questions
