1. 50 degree angle I believe
2. 150 degree angle
3. 45 degree angle
Sorry if this doesn't help but, with no context about the answers they have given you I can't fully help. Try using a protractor like this down below.
Have a good day!
Answer:
a)13x+3
b) -3x-13
c)4x^2-24
d)-3x^2 +3x
Step-by-step explanation:
a) combine like terms
5x-3+8x+6 so combine the -3 and +6 and 5x and 8x
So 13x+3
b)There is an invisible one in front of (2x-5) and an invisible -1 in front of (5x+8). Distribute these.
2x -5 - 5x -8
So -3x-13
c) Distribute the four to everything in the brackets.
4(x^2-6) becomes 4x^2-24
d) Distribute:
-3x (x-1) becomes -3x^2 +3x

Given, Annapolis, Maryland has an approximate population of 36,000.
And Columbus, Ohio has an approximate population of
.
First we have to multiply
.

We can see the population of columbus is larger than population of Annapolis.
Now we will divide the population of Columbus by the population of Annapolis to find how much times the population of columbus is larger. We will get,
= 20.28 ( Approximately taken upto two decimal place)
So it is more than 20 times.
We can say, The population of columbus is approximately 20 times larger than Annapolis.
We have got the required answer.
Option 3 is correct.
