What value of n makes the equation true ?

-18

Step-by-step explanation:

2/3n=-12

(multiply both sides by the reciprocal)

(3/2)(2/3)n=(3/2)(-12)

( the 3/2 and 2/3 cancel)

n=-18

here you hope this .

step-by-step explanation:

hypotenuse = √(15² + 8²)

=  √(225 +64)

=  √(289) = 17

sin(x) = cos(y) = 8/17

they are identical so long as you are doing the sine of one angle and the cosine of the only other angle that isn't the right angle.

i think is g(1)=-1.

hope that i can
