R + 3 1/2 = -4 2/3
alexandr402 [8]

Answer:

R = -8 1/6

Step-by-step explanation:

We'll solve the given equation for R.

Subtract 3 1/2 from both sides of the equation, to isolate R:

           R +  3 1/2  -  3 1/2 = -4 2/3  - 3 1/2, or

            R = -4 2/3 - 3 1/2

The LCD here is 6, which is the product of 3 and 2.  Converting the fractions to denominator 6, we get:

              R = -4 4/6 - 3 3/6, or

               R = -7 - 7/6, or R = -7 - 1 1/6, or -8 1/6

So sine of complementary angle also has same value as cos 42.

Rút gọn (x-4) (x-3) -x(x+5) +82
WINSTONCH [101]

Answer:

-12x + 94

Step-by-step explanation:

Simplify:

\left(x-4\right)\left(x-3\right)-x\left(x+5\right)+82

=x^2-7x+12-x\left(x+5\right)+82

=x^2-7x+12-x^2-5x+82

=x^2-x^2-7x-5x+12+82

=-7x-5x+12+82

=-7x-5x+94

=-12x+94
