Answer:
The answer is 7.
Step-by-step explanation:
You solve this by using PEMDAS. You solve the multiplication and division before addition and subtraction leaving you with 6 + 5 - 4. You then do addition/subtraction from left to right giving you 11-4. Ultimately your final answer will be 7.
The area of the triangle would be 27.71 cm^2
The answer to your problem is 1.571
Because this person is isolating for x, they would add 3 to each side, to have x by itself.
This will leave them with the equation 3x=18
So 3x=18 is most likely the next step
