Simplify (sin^2 θ + cos^2 θ)(sin θ + cos θ)

sin θ + cos θ

Step-by-step explanation:

There is a trigonometric identity that states that:

sin²θ + cos²θ = 1

Now, for the given we have:

(sin²θ + cos²θ) (sin θ + cos θ)

Applying the above identity, we would find that the expression becomes:

(1) (sin θ + cos θ) which is equal to sin θ + cos θ

Hope this helps :)

x= -3

step-by-step explanation:

step 1: simplify brackets

4 - x - 1 = 6

step 2: simpilfy

3 - x = 6

step 3: subtract 3 from both sides

-x = 6 - 3

step 4: simpilfy 6 - 3

-x = 3

step 5: multiply both sides by -1

x = -3
