The simplified solution to this equation is 5x - 115.
Answer:
146°
Step-by-step explanation:
The measure of the arc EF is equal to the angle subtended at the centre.
That is EF = 146°
Answer:
b. 
Step-by-step explanation:
Here we are given 
and are asked to simplify it. We are going to apply the law of exponents which says that
Hence applying this rule in our problem we get, where a=y and n=3
Hence our C) Option is correct
First, put parenthesis around the first two numbers and the last two numbers.
(20g³+24g²) (-15g-18)
Then, take out the greatest common factor of both parenthesis.
4g²(5g+6)-3(5g+6)
You then separate the numbers outside the parenthesis and the numbers in the parenthesis.
(5g+6) (4g²-3)
Then you simplify the second set of numbers. Since the set of numbers can't be simplified, you would leave this problem as it is. I hope this makes sense.
