Answer 2

It seems like you've provided a series of mathematical expressions, and it looks like you want to simplify or solve them. Let's work through each one:

2. 276m (172m + 14m): To simplify this expression, you can distribute the 276m to both terms inside the parentheses. 276m * 172m = 47472m^2 276m * 14m = 3864m^2 So, the simplified expression is 47472m^2 + 3864m^2, which can be further combined: 47472m^2 + 3864m^2 = 51336m^2

3. 262 + (132 - 5z) + z: First, simplify the expression inside the parentheses: 132 - 5z + z = 132 - 4z Now, you can add this result to 262: 262 + (132 - 5z) + z = 262 + (132 - 4z) = 394 - 4z

4. 42x + 45 + 8x + 45: Combine like terms by adding the coefficients of 'x' and the constants separately: 42x + 8x = 50x 45 + 45 = 90 So, the simplified expression is 50x + 90.

5. 204b + 30b + 6b + 56: Combine like terms by adding the coefficients of 'b' and the constant: 204b + 30b + 6b = 240b Now, add 240b to 56: 240b + 56 = 296b

So, the simplified expressions are:

2. 51336m^2
3. 394 - 4z
4. 50x + 90
5. 296b
