Answer: x=3
Step-by-step explanation: Step 1: Simplify both sides of the equation.
21x−5=7+17x
21x+−5=7+17x
21x−5=17x+7
Step 2: Subtract 17x from both sides.
21x−5−17x=17x+7−17x
4x−5=7
Step 3: Add 5 to both sides.
4x−5+5=7+5
4x=12
Step 4: Divide both sides by 4.
= 
So Final Answer: <u>x=3</u>

Answer:
b. continuous random variable
Step-by-step explanation:
Speed is a common continuous variable and the value is always random.
It is continuous because there is always another speed value between two speed values. For example, a car travelling at the rate of 50 mils per hour will either increase or decrease its speed at a continuous rate. No speed can drop suddenly form 50mph to 20mph.
It is random because although there might be speed limit, the speed recorded by the Highway patrol officer willl always be random in value.
Well CD and CB are both equal to each other because they’re the same angles , it’s a reflection
