5 13/8 or 6 5/8

Step-by-step explanation:

2 3/4 + 3 7/8

since we are add we need to get a common denominator(bottom number)

I know that 2 × 4 = 8

3/4 × 2 = 6/8

new problem is

2 6/8 + 3 7/8

2+3=5

6/8 + 7/8 = 13/8

5 13/8

you may need to simplify you answer

13 - 8 = 5

6 5/8

step-by-step explanation:

∆abc has the points a(1, 7), b(-2, 2), and c(4, 2) as its vertices. formed with the point d(1, 2) as its third vertex, then ∆abd is triangle.
