30 is 60% of the number 50. The answer is 50
Answer:
Every year they are losing 600 people a year.
Step-by-step explanation:
You take 50,000/100= 500 x 1.2=600
Remark
You'll see it a whole lot easier if you make a substitution so that it looks like something you have already seen
Solution
let y = x^2
x^4 = x^2 * x^2
x^4 = y * y
x^4 = y^2
Now the expression becomes
y^2 + 8 y - 9 = z
(y + 9)(y - 1) = z
Now put the x^2 back in.
(x^2 + 9) ( x^2 - 1) = z
x^2 - 1 becomes x + 1 and x - 1. At this level x^2 + 9 can't be factored.
Answer
(x^2 + 9) (x + 1)(x - 1)
Answer:
Step-by-step explanation:
hello :
it the width and length the Integer number you have two rectangle :
