<u>Answer:</u>
-4
<u>Step-by-step explanation:</u>
We are given the following expression which we are to solve:
![( - 4 ) 5 - ( - 6 ) ( - 4 ) + 4 0](https://tex.z-dn.net/?f=%20%28%20-%204%20%29%205%20-%20%28%20-%206%20%29%20%28%20-%204%20%29%20%2B%204%200%20)
Since this expression includes brackets as well has plus and minus signs, so we will follow the standard order of operations to solve this expression.
Solving the brackets first to get:
![( - 2 0 ) - ( 2 4 ) + 4 0](https://tex.z-dn.net/?f=%20%28%20-%202%200%20%29%20-%20%28%202%204%20%29%20%2B%204%200%20)
Now adding all the terms up to get:
-4
A. has no solutions.
B. has many.
C. has many.
D. has many.

Step-by-step explanation:
Can you help me with this please
-42=5(2c+9)-3(c+8)
-42 - 7c + 21 = 0
c = -(-63)/-7
c = -9
The present age of George is 25 years and the present age of Harry is 17 years
For given question,
Let x be the age of George and y be the age of Harry.
George is now 8 years older than harry.
So, we get an equation,
x = y + 8 ...................(1)
After 5 years the age of George will be x + 5 and the age of Harry will be y + 5
Two years ago the age of Harry = y - 2
In 5 years George will be twice as Harry was 2 years ago.
So we get an equation,
x + 5 = 2(y - 2) ..............(2)
Substitute the value of x in equation (2)
⇒ x + 5 = 2(y - 2)
⇒ y + 8 + 5 = 2y - 4
⇒ y + 13 = 2y - 4
⇒ y = 17
Substitute the above value of y in equation (1)
⇒ x = 17 + 8
⇒ x = 25
Therefore, the present age of George is 25 years and the present age of Harry is 17 years
