Tan=o/adj
Tan=60/b
B=60/tan(68)
I don't have a calculator on me but you should be able to do it from there
4x+12=16
4x=4
x=1
or
-(4x+12)=16
-4x-12=16
-4x=28
x=-7
answer Choice C is correct
Instead of X put 5 and instead of y put 2
5+6(2)
5+12= 17
Examples :
(-2)^3 = (-2)(-2)(-2) = - 8
(-3)^4 = (-3)(-3)(-3)(-3) = 81
(-1)^5 = (-1)(-1)(-1)(-1)(-1) = -1
** if the exponent is an even number, the answer will be positive. if the exponent is an odd number, then the answer will be negative
** but keep in mind....if the negative is not included with the base..
-(5^2) = - 25....but (-5^2) = 25
Answer:
-1
