klasskru [66]

Answer:

GCF = 3

Factor = 3(x^2-100)=0

Solutions are: x = 10, -10

Step-by-step explanation:

You have to factor out GCF which is 3 which then makes the equation 3(x^2-100)=0. After that you basically have (x^2-100)=0. Which then you solve for x which is a difference of squares and the answers are 10 and -10 for x.

Answer:

$x = 54$

$y = 0.225$

Detailed steps:

We know that the number of total events is

$n = 80$

and that the probability of a certain event E (for example, "the enemy drops two objects") is computed as the number of times event E occurred, divided by the total of events N=80.

Then:

$0.675 = \frac{x}{80}$
