Answer:
a = -5.
Step-by-step explanation:
(3x + 2)(x + 1)
= 3x(x + 1) + 2(x + 1)
= 3x^2 + 3x + 2x + 2
= 3x^2 + 5x + 2
So the remainder a = 3x^2 + 5x - 3 - (3x^2 + 5x + 2)
= -3 - 2
= -3 - 2
= -5 (answer)
Answer:
Step-by-step explanation:
First convert the transmit power into μW, considering 1 W = 1000000 μW:
- 0.35 W = 0.35*1000000 μW = 350000 μW
Find how many factors of 10 the power dropped:

Answer:
Step-by-step explanation:
Expand brackets.
Apply radical rule : 
The sum of angle AOB and angle BOC is equal tot he angle of AOC so
6x+5 +4x-2 = 8x+21
10x+3=8x+21
Subtract three and 8x from both sides
2x=18
Divide by two
x=9
