You would factor a 5x out of the numerator sine there is a 5x in 5x^3, 10x^2 and 15x. when you factor, it should be 5x( x^2+2x+3). The 5x on top and bottom would then cancel out, leaving x^2+2x+3 as you answer.
Answer:
60
Step-by-step explanation:
To find the mean;
add up the data
(50+60+60+70) =240
Then divide by the number of data points
240/4 = 60
The mean is 60
2c - 5 < -21 - 2c |add 5 to both sides
2c < -16 - 2c |add 2c to both sides
4c < -16 |divide both sides by 4
c < -4
Answer:
Step-by-step explanation:
