Let's factor all four of these before we multiply.
x² - 25 We want two numbers that add to -25 and multiply to 0.
= (x+5)(x-5)
x² - 2x
Both terms are divisible by x.
= x(x-2)
x - 2unfactorable
x² + 5x
Both terms are divisible by x.
= x(x+5)
Now we have this:
Let's go ahead and multiply across.
Cancel out the (x+5) and (x-2) from the top and the bottom.
Answer:
<h2>
</h2>
Step-by-step explanation:
Remove unnecessary parentheses
When there is a (-) in front of an expression in parentheses, change the sign of each term in the expression
Collect like terms
Add the numbers
Use the commutative property to reorder the terms
Hope this helps...

If f = {(4, 2), (6, 1), (8, 4), (10, 2), (12, 5)}, what is the range
UNO [17]
Answer:
Range = {2,1,4,5}
Step-by-step explanation:
When a function is given in the form if a relation. i.e. ordered pairs.
When the function is given in the form of ordered pairs then the set of first elements i.e. x-coordinates of all ordered pairs forms domain while the set of second elements i.e. y-coordinate of all ordered pair is called range.
So in the given function:
Range = {2,1,4,5}
The repeating values are only written once..
Since it is a square, the angles are 90 degrees. The diagonals would bisect the angle in half so the angle PRS would be equal to 45 degrees.
