Call x the smallest of the three numbers, then:
x + (x+1) +(x+2) = -27
x + x + 1 + x + 2 = -27
3x+3 =-27
3x = -27 -3
3x = -30
x = -30/3 = -10
The three numbers are: -10, -9 and -8.
Answer:
a) x = 5
b) x = 4
Step-by-step explanation:
a) x = 5
You can get this with a calculator if you need by using the log function.

x = 5
b) x = 4
According to the product rule of exponents: 
So, x + 11 = 15 --> x = 4
( 8 - 2i ) * ( 5 + i ) = 40 + 8i - 10i - 2* i^2 = 40 -2i - 2 * ( -1 ) = 40 + 2 - 2i = 42 - 2i;
THE ANSWER IS D. 42 - 2i
