Im not sure about this one but i think x is 60 since the line Ed basically bisects the angle E which also bisects the line GH in half so that 62=x+2 and then solve for the equation
The answer to that question would be the number 3 on the left side
Answer:
5-46i
Step-by-step explanation:
1. Multiply (10-4i) and (4-5i), I recomnd using foil:
40-50i-16+20i^2 + (-15+20i)
2. Remove the parenthesis around -15+20i
*we can do this since there is a "+":
40-50i-16+20i^2 + (-15)+20
3. Simplify i^2
* i^2 is -1 by textbook defination:
40-50i-16+20(-1) + (-15)+20
4. Simplify
40-50i-16-20 + (-15)+20
6. Combine like terms:
-5-50i-16i+20i
5-46i
And the problem is done
Answer: D
A is just a survey (yes or no answers), B is more of a factual question (not concerning a set or population), and C is the same as B
