A. If you're adding numbers with exponents with the same base, keep the same base and add the values of the exponents together.
3^2 * 3^4 = 3^(2+4) = 3^6
D) 2.1+2x=7.5
All the sides added together will equal the perimeter
I believe the answer is the first option. 1 to 3 with intervals of 1.
Hope this helps!
Check the picture below
notice, the run is half 35
recall slope = rise/run
To get the difference between the two diameters, all you have to do is subtract the smaller diameter (Mercury) from the larger diameter (Saturn) as follows:
Difference between the two diameters =diameter of Saturn-diameter of Mercury
Difference between the two diameters = (1.2*10^5) - (4.9*10^3)
Difference between the two diameters = 115100 km
