Answer:
A
Step-by-step explanation:
2x/x-1
The equation seems to be
1
-------- = 5 ^ (x + 4)
25
In that case, this is the solution, stept by step:
1) factor 25: 25 = 5^2
1
=> ----------- = 5^(x + 4)
5^2
2) invert 5^2
=> 5^(-2) = 5^(x+4)
3) Given that the bases are equal, the exponents also have to be equal:
=> - 2 = x + 4
3) transpose +4:
=> - 2 - 4 = x
=> x = - 6
Answer: - 6
Answer:
A princess is stuck at the top of a tower that is 20 ft tall. To get down she shoots an arrow with rope attached into the ground and it lands 15 ft away from the tower. how long is the rope to safely guide her onto the ground.
Step-by-step explanation:
using the Pythagorean theory which is a squared plus b squared equals c squared you will see that 20 squared plus 15 squared will equal 625. Once you have that answer you find the square root of 625 which will give you your overall answer of 25.
