Answer: The different possible solutions are 42, 21, 31 and 80.
Explanation:
The given expression is,
![7+3\cdot 4+2](https://tex.z-dn.net/?f=7%2B3%5Ccdot%204%2B2)
Case 1.
![(7+3)\cdot 4+2=10\cdot 4+2](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D10%5Ccdot%204%2B2)
![(7+3)\cdot 4+2=40+2](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D40%2B2)
![(7+3)\cdot 4+2=42](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%204%2B2%3D42)
Case 2.
![7+(3\cdot 4)+2=7+12+2](https://tex.z-dn.net/?f=7%2B%283%5Ccdot%204%29%2B2%3D7%2B12%2B2)
![7+(3\cdot 4)+2=21](https://tex.z-dn.net/?f=7%2B%283%5Ccdot%204%29%2B2%3D21)
Case 3.
![7+3\cdot (4+2)=7+3\cdot 8](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D7%2B3%5Ccdot%208)
![7+3\cdot (4+2)=7+24](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D7%2B24)
![7+3\cdot (4+2)=31](https://tex.z-dn.net/?f=7%2B3%5Ccdot%20%284%2B2%29%3D31)
Case 4.
![(7+3)\cdot (4+2)=10\cdot 8](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%20%284%2B2%29%3D10%5Ccdot%208)
![(7+3)\cdot (4+2)=80](https://tex.z-dn.net/?f=%287%2B3%29%5Ccdot%20%284%2B2%29%3D80)
To find the value of f(3) we need to follow the below steps :
Step 1 : First plot the graph of f(x)
Step 2 : We need to find f(3) or the function value at x = 3 therefore, in the graph locate the point (3,0)
Step 3 : Draw a line parallel to Y-axis passing through the point (3,0) .
Step 4 : Now there exists two cases :
If the drawn line do not intersect the graph of f(x), then no value of f(3) exists for the given function of x
If the drawn line intersects the graph, then the intersection point is marked and a line parallel to x - axis is drawn passing through that marked or intersection point. And the line where it intersects the y - axis is our required value of f(3).
If this is wrong than I guess I wasn't smart enough :)
Answer:
The expression (2 x 3) + 13 - 1 on simplifying gives 18.
Step-by-step explanation:
Here, the outcome of the expression is 18.
Using at least three operations.
Here, we use three operations Addition = '+' , Subtraction = '-' and
Multiplication = 'X'
Take the number 2 and multiply it with other number 3.
We get 2 x 3 = 6
Take the product, add it with another number 13
So, 6+ 13= 19
Take the resultant and subtract 1 from it.
We get 19 - 1 = 18
⇒The combined expression is (2 x 3) + 13 - 1 = 18
The above expression on simplifying gives 18.
