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:
135
Step-by-step explanation:
Using the given recursive rule, then
= 
(- 9) = 
(- 9) = - 15
= (- 9) = - 15 × - 9 = 135
3 I think lol

Though, I’m not sure
Check the picture below.
make sure your calculator is in Degree mode.
Answer:
x = 3, y = 10.
Step-by-step explanation:
The 2 triangles are similar so the corresponding sides are in the same ratio.
x/6 = 4/8
x/6 = 1/2
x = 6/2 = 3.
y/5 = 8/4 = 2
y = 5*2 = 10,
