Answer:

-x^2 + 4

Step-by-step explanation:

Multiply; (2 + x)(2 - x)

= 4 - 2x + 2x - x^2

Combine Like Terms; 4 (-2x + 2x) -x^2

= 4 - x^2

Put in Final Form;

= -x^2 + 4

If you need to solve for X;

Subtract 4

-4 = -x^2

Divide both sides by -1;

4 = x^2

Square root both sides;

2 = x

Express sin UU as a fraction in simplest terms.
alukav5142 [94]

The expression of sinU as a fraction is 12/13

Find the diagram attached.

To get the fraction represented by sinU, we will use the SOH CA TOA identity.

From the diagram;

  • Hypotenuse = SU = 13
  • Opposite = ST = 12 (angle opposite to m<U)

Since sin theta = opp/hyp

SinU = ST/SU

SinU = 12/13

Hence the expression of sinU as a fraction is 12/13
