Question

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

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:
\[
\boxed{-4x + 44}
\]

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