Step-by-step explanation:
So, √69 is between 8 and 9 . Since 69 is much closer to 64 than to 81 , the best whole number estimate is 8
I'm not positive, but wouldn't it be 1 because they are all like terms? When like terms are similar you combine them together do you not?
They are not like terms. So false.
5x^2y is not the same as 7xy^2 because the exponent is on different variables.

The slope is 1 :) but the equation is y= 1x + 1
Answer:
Step-by-step explanation:
We need to figure out how far Eric's car takes him in 1 rotation based on the diameter of his tire in feet. If the diameter of the tire is 18", then it is 1.5'. The circumference will tell us the distance 1 rotation of his tires will take him:
C = 3.1415(1.5) so
C = 4.71225 feet is how far he goes in 1 rotation. If he travels 88 feet in 1 second, we can figure the number of rotations by dividing 88 by 4.71225 to give us the unit rate (or, rotations per second his car makes). This quotient is 18.67 feet per sec, which rounds to 19, choice B.
