(u^2 - 4) / (u-6)(u-2)
Resriction u ≠ 6 and u ≠ 2 (because the denominator cannot be equal lto zero)
Simplification
u^2 - 4 is a difference of two squares, then you can factor it as the product of (u+2)(u-2). So, you can write the expression as:
(u+2)(u-2) / (u-2)(u-6)
Simplify u -2 (because it appears in the numerator and the denominator)
(u + 2) / (u -6), with u ≠2 and u≠6

Answer:
Number of carnations = 6
Step-by-step explanation:
Let the number of carnations school band buys from florist be x.
Cost of each carnation = $0.50
Total cost for x number of carnations = $0.50x
Also , delivery cost = $15
So, total cost on buying x number of carnations from florist = 0.50x + 15
Now,
School band sells carnations at a price of $3 each.
Total revenue they get get after selling x number of carnations = $3x
We need to find that , when will the cost of the carnations be equal to the revenue from selling them.
i.e 3x = 0.50x + 15
or 3x - 0.50x = 15
or 2.50x = 15
or x = 
or x = 6
so on selling 6 carnations cost of carnation reach to the point where it is equal to revenue
Answers:
The expression is equivalent to a rational number.
The expression represents the sum of two rational numbers.
Answer:
6. (a) 7. (b) Im pretty sure 8. (d)
Step-by-step explanation:
A real number is basically any number whatsoever, meaning a real number can also be irratonal.
7. pi is 3.1415926535... but doesn't repeat so it doesn't go on a number line, the sq root of -16 is -4 which has a place on the line, and the repeating decimal would have no place on a number line.
8. irrational means it repeats without a pattern, such as pi (3.1415926535...) which is why the answer is d
