Area of a triangle is calculated by using the formula A=1/2bh
A= 1/2 (8.2) (5)
A=1/2 (41)
A=20.5 or 20 1/2, whichever way you think your teacher wants it.

The area of a triangle is half the base × height. So you multiply 8.2 × 5 to get 41. And when you divide that by 2, you get 20.5

When do you get an answer to a system of linear equations that has one solution, no solution and infinitely many solutions?

meriva

Answer:

Step-by-step explanation:

One solution: when two lines intersect in exactly one point.

Infinitely many solutions: When one of two lines can be shown algebraically to be exactly the same as the other. The two lines coincide.

No solution: The two lines have the same slope but different y -intercepts. They can't and don't intersect.
