The value of the expression (-4x - 4) + (-4x - 10) is -8x - 14

<h3>What are expressions?</h3>

Expressions are mathematical statements that are represented by variables, coefficients and operators

<h3>How to determine the value of the expression?</h3>

The expression is given as

The sum of (-4x - 4) and (-4x - 10)

This can be represented as

(-4x - 4) + (-4x - 10)

Remove the bracket

So, we have

(-4x - 4) + (-4x - 10) = -4x - 4 - 4x - 10

Collect the like terms

So, we have

(-4x - 4) + (-4x - 10) = -4x - 4x - 4 - 10

Evaluate the like terms

So, we have

(-4x - 4) + (-4x - 10) = -8x - 14

Hence, the value of the expression (-4x - 4) + (-4x - 10) is -8x - 14

1. Kyle has a baseball game after school. He drives 6 miles due west from his home to school. After school, he drives 5 miles du

Answer:

D. 7.8 miles.

Step-by-step explanation:

So, to solve this, you need to use the Pythagorean theorem to find the distance from the baseball field to his home. You know two of the sides of the triangle formed, 6 and 5. The Pythagorean theorem is a² + b² = c². In this case, it would be 6² + 5² = c². If you solve this, you would find that c is 7.81024967591. Just round it to the nearest tenth like instructed. This would get you 7.8 as the answer.

Extra work just in case:

6² + 5² = c²

36 + 25 = c²

61 = c²

$\sqrt{61}$ = $\sqrt{c^{2} }$
