Answer:

x = 22 (see explanation!)

Step-by-step explanation:

Just with any algebraic equation, you will want to isolate the variable (x). Here's a step-by-step to show you how it's done:

1/7(x + 6) = 4

Multiply by 7 to get rid of the 1/7 (since 7 * 1/7 = 7/7 = 1)

7*1/7(x+6) = 7*4

x+6 = 28

Now, subtract 6 from both sides to isolate x:

x + 6 - 6 = 28 - 6

Finally:

x = 22

Factor the algebraic expression below in terms of a single trigonometric function. sin 2x + sin x - 2

Pie

Answer:

The factored form is (sin x +2)(sin x-1)

Step-by-step explanation:

We have been given the trigonometric function $\sin^2 x +\sinx-2$

We can factor this by AC method. In AC method we multiply the term a and c and then write the middle term b in such a way that the sum/difference is equal to the product 'ac'

Using the method, we can write sinx as 2sinx -sinx

$\sin^2 x +2\sinx-\sin x-2$

Now, we group the first two terms and the last two terms

$(\sin^2 x +2\sinx)+(-\sin x-2)$

Now, we take GCF from each group

$\sin x(\sin x +2)-1(\sin x+2)$

Factor out (sinx+2)

$(\sin x +2)(\sin x-1)$

Therefore, the factored form is (sin x +2)(sin x-1)
