Solve the following expression:

$9(5x - 5) + 7x$

-Use <u>Distributive Property</u>:

$9(5x - 5) + 7x$

$45x - 45 + 7x$

Answer:

<h2>x = 5√3 inches</h2>

Step-by-step explanation:

Since the triangle is a right angled triangle we can use Pythagoras theorem to find the missing side x

Using Pythagoras theorem we have

${a}^{2} = {b}^{2} + {c}^{2}$

where a is the hypotenuse

Substitute the values into the above formula

The hypotenuse is 10 inches

We have

${10}^{2} = {5}^{2} + {x}^{2}$

${x}^{2} = {10}^{2} - {5}^{2}$

${x}^{2} = 100 - 25$

${x}^{2} = 75$

We have the final answer as

<h3>x = 5√3 inches</h3>

Hope this helps you

Let A be the event $A=\{choosing \;an \;odd \;number\}$ and B be the vent $B=\{choosing \;an \;even \;number\}$ . Since the intersection of the events $A\cap B=\phi$ , the events A and B are mutually exclusive.

The number is either odd or even. Since $P(A)+P(B)=1$ , the events are mutually exclusive and exhaustive.

Correct choice is "the number is either odd or even".
