2=n-(2n+3). solve for n. give steps as well.

2=n-(2n+3)

pretend that there is a -1 in front of the bracket

2=n-1(2n+3)

multiply the bracket by -1

(-1)(2n)=-2n

(-1)(3)=-3

2=n-2n-3

2=-n-3

move -3 to the other side

sign changes from -3 to +3

2+3=-n-3+3

2+3=-n

5=-n

multiply both sides by -1 to get +n

5(-1)=-1(-n)

n=5(-1)=-5

n=-5

i have no clue at all sorry

step-by-step explanation:

step-by-step explanation:

use pothagarean therom

a^2+b^2=c^2 so first ac

acm is a right triangle because c= 90°

and am (the hypotenuse or c) =16+9 =25

but there is not enough info we need another angle or side length
