Question

1)17ab+17ab+17ab 2)2m+2m+2m 3)(c-2d)+(c-2d)

Answer 1

1) 17ab + 17ab + 17ab = 17ab*(1 + 1 + 1) = 17ab*3 = 51ab.

2) 2m + 2m + 2m = 2m*(1 + 1 + 1) = 2m*3 = 6m.

3) (c - 2d) + (c - 2d) = c - 2d + c - 2d = 2c - 4d.

Answer 2

It looks like you've provided some mathematical expressions. Let's simplify them:

1. 17ab + 17ab + 17ab When you combine like terms, you can add the coefficients: 17ab + 17ab + 17ab = 51ab

2. 2m + 2m + 2m Similar to the first expression, combining the coefficients gives: 2m + 2m + 2m = 6m

3. (c - 2d) + (c - 2d) In this case, you're adding two similar expressions: (c - 2d) + (c - 2d) = 2c - 4d

So, the simplified expressions are:

1. 51ab
2. 6m
3. 2c - 4d
