Prove that sin^3x+sincos^2x=sinx

Step-by-step explanation:

factor sin(x) out of the equation

sin(x) * () = sin(x)

Use the trigonometric identity

sin(x) * 1 = sin(x)

sin(x) = sin(x)

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6

-2

7 - 9 = -2

reversed:

-2 + 9 = 7
