Answer:
(x-3) (x+5) => x*x+5x-3x-15
=> x*x+2x-15
Step-by-step explanation:
The answer is 6 because 6 to the second power is 6•6. 6•6 is 36. 5+1 is 6. So, 36 divided by 6 equals 6.

Answer:
Statement 3
Step-by-step explanation:
<u>Statement 1:</u> For any positive integer n, the square root of n is irrational.
Suppose n = 25 (25 is positive integer), then

Since 5 is rational number, this statement is false.
<u>Statement 2:</u> If n is a positive integer, the square root of n is rational.
Suppose n = 8 (8 is positive integer), then

Since
is irrational number, this statement is false.
<u>Statement 3:</u> If n is a positive integer, the square root of n is rational if and only if n is a perfect square.
If n is a positive integer and square root of n is rational, then n is a perfect square.
If n is a positive integer and n is a perfect square, then square root of n is a rational number.
This statement is true.
