Simplify the expression 19 + 6x - 10x + 5^2

Question

A. -4x + 44
B. -16x + 44
C. 16x - 44
D. -4x + 29

Answer 1

To simplify the expression $19+6x-10x+5^2$, we follow these steps:

1. Start with the original expression: $$19+6x-10x+5^2$$

2. Calculate $5^2$: $$5^2=25$$

   So now the expression becomes: $$19+6x-10x+25$$

3. Combine like terms. First, combine the constants $19+25$: $$19+25=44$$

4. Now combine the $6x$ and $-10x$: $$6x-10x=-4x$$

5. Putting it all together, we have: $$-4x+44$$

Thus, the simplified expression is: $$\boxed{{\displaystyle -4x+44}}$$

The correct answer is A. -4x + 44.
