Answer:
k = 13
Step-by-step explanation:
20 ^ k / 20^4 = 20^9
knowing the laws of exponents, diving two numbers of the same base with exponents is like subtracting the exponents, so
k^x / k^y
= k ^ (x - y)
apply that knowledge here
20 ^ k / 20 ^ 4 = 20 ^ 9
20 ^ ( k - 4 ) = 20 ^ 9
now the bases have no use here so ignore them, and just calculate the exponents
k - 4 = 9
solve using inverse operations
k - 4 = 9
+4 +4
k = 13
The root is 10 because 2x5 is 10 so that’s ur answer
Solve the equation for x. X+48=649*(1/x)
Answer:
Choice A
Step-by-step explanation:
You can rule out choices B and D because they do not have 6 sides which your prism does. You can forget about C being correct because it doesn't have 4 long sides.
Answer:
Negative
