Answer:
9
Step-by-step explanation:
This is because of the distributive property.
The outside number is multiplied by each inside number.
So, if it's 9(5x+8y), then do 9*5x which is 45x and 9*8y which is 72y.
50,000 mm=5,000 cm=500 decimeter=50 m=5 decameter
so both are equal.
I'm pretty sure it is C
1/(√x-5)*(√x+5)/(√x+5)
