How would you conjugate the verb hablar?

Hablar, or "to speak", is a verb ending in "ar". Verbs ending with "ar" can be conjugated using this chart as follows: o (yo) amos (nosotros) as (tú) a (Ud., él, ella) an (ellos, ustedes) Therefore we would conjugate hablar like so: Yo hablo. Tú hablas. (Ud., Él, Ella) habla. Nosotros hablamos. (Ellos, Ustedes) hablan.

### Subject: Geometry

You are given a right triangle with side a = 2 and side b = 4. Find side c.

We know that we can solve a right triangle using the Pythagorean Theorem, which is a^2 + b^2 = c^2. So if we plug in our values, we should get 2^2 + 4^2 = c^2. We then simplify that equation to 4 + 16 = c^2. We add 4 and 16 to get 20 = c^2. To get c by itself, we have to take the square root of both sides of the equation. Therefore c = sqrt of 20.

### Subject: Algebra

You are given y = 4x + 2x + 3. x = 2 Find y.

First you need to simplify your equation. We can combine like-terms. The like-terms in this equation are 4x and 2x. 4x + 2x = 6x. Our newly written equation is y = 6x + 3. We can see that we are given x = 2. We need to substitute x into the equation. So, our new equation will look like this. y = 4(2) + 2(2) + 3. Once we simplify, we get y = 8 + 4 + 3. Our final step is to simplify once more to get to value of y. So, y = 15.
