First, you would solve the parentheses.
72-(7+8)*4
72-(15)*4
Then, you would do multiplication.
72-60=
12
Hope this helps!
Which of these numbers are divisible by 9? 7,625 4,932 9,180 2,969 9,180 and 4,932 2,969, 9,180, and 7,625 9,180 and 7,625 2,969

Answer:
The answer to your question is below:
Step-by-step explanation:
A number is divisible by 9 if the sum of all the individual digits is evenly divisible by 9.
7,625 example 7 + 6 + 2 +5 = 20 it's not divisible by 9
4,932 4 + 9 + 3 + 2 = 19 it's not divisible by 9
9,180 18 it is divisible
2,969 26 it's not divisible by 9
9,180 18 it is divisible
4,932 18 it is divisible
2,969 26 it's not divisible by 9
17-6 x 10/2+ 12
17-60/2+12
17-30+12
17-18
= -1
From the prime factorization of 49, we get 7*7. From 196, we get <span>2*2*7*7. From 343, we get 7*7*7. The greatest "overlap" or common factors are 7*7, or 49.</span>
Thus, the greatest common factor is 49.
The first equation is 
(Equation 1)
The second equation is 
(Equation 2)
Putting the value of x from equation 1 in equation 2.
we get,
by simplifying the given equation,
Using discriminant formula,
Now the formula for solution 'x' of quadratic equation is given by:
Hence, these are the required solutions.
