Answer:
24
Step-by-step explanation:
8*3=24
For this case, the first thing we must do is to group similar terms.
We have then:
n (9 + 15) + (12-6)
Rewriting:
24n - 6 ft
Answer:
(9n + 12) ft + (15n -6) ft = 24n - 6 ft
Answer: 165,900 km
Step-by-step explanation:
diameter is a straight line between two points on the circumference of a circle that passes between the center of the circle.
so if a penny has a diameter of 7.9 x 10^-5 km, and when placed end to end will require 2.1 x 10^9 pennies to circle the equator once, that means;
the approximate length of the equator will be:
7.9 x 10^-5 km x 2.1 x 10^9 pennies
= 165,900 km
