To find the area of a triangle, multiply the base by the height, and then divide by 2. The division by 2 comes from the fact that a parallelogram can be divided into 2 triangles. For example, in the diagram to the left, the area of each triangle is equal to one-half the area of the parallelogram.

Solve for x: 3/2 + 1/2x =2x

<h3>Solve for x: 3/2 + 1/2x =2x</h3>

$\huge{ \boxed{ \bf{ \red{Solution:-}}}}$

$\bold{ \frac{3}{2} + {\frac{1}{2} x = 2x}}$

$\bold{ ⇒\frac{3}{2} + {\frac{x}{2} = 2x}}$

$\bold{⇒\frac{3 + x}{2} = 2x}$

$\bold{⇒3 + x = 2(2x)}$

$\bold{⇒3 + x = 4x}$

$\bold{⇒3 = 4x - x}$

$\bold{⇒ \frac{3}{3} = x}$

$\bold{ \therefore{x = 1}}$

Please help with this question

natita [175]

Answer:

$12\sin{(2\theta)}\cos{(\theta)}$

Step-by-step explanation:

The appropriate trig identity is ...

$\sin{a}+\sin{b}=2\sin{\left(\dfrac{a+b}{2}\right)}\cos{\left(\dfrac{a-b}{2}\right)}$

Here, you have a scale factor of 6 and a=3θ, b=θ. Filling in these values gives ...

$6\sin{3\theta}+6\sin{\theta}=12\sin{\left(\dfrac{3\theta+\theta}{2}\right)}\cos{\left(\dfrac{3\theta-\theta}{2}\right)}\\\\=12\sin{(2\theta)}\cos{(\theta)}$

|-4| - 8 + 10 = ??? answer for points

Elis [28]

Answer:

Step-by-step explanation:

As you might know, the two lines surrounding the -4 represent the absolute value, which is basically the distance from 0, and the distance is always positive. To clear any confusion, the absolute value of positive number will not be it's opposite because remember, distance is always positive, so absolute value is always positive (because it is basically the distance from zero).

To help, here is an example (that is not related to the problem!):

|-6| = 6

|6| = 6

Now, back to the problem...

Since you now know that the absolute value is always positive, |-4| would equal 4. So now you have:

4 - 8 + 10 = ???

From here, you can just solve and the answer is 6, so:

4 - 8 + 10 = 6

You final answer is 6.

Hope this helped somehow :D
