Answer:
(x-3)
Step-by-step explanation:
we have

step 1
Simplify the numerator
Complete the square
Equate the equation to zero




Rewrite as perfect squares

Take square root both sides




therefore

substitute in the numerator

Answer: A then 0.700 .7 .70
Step-by-step explanation:
Answer:
10x+200
375
Step-by-step explanation:
subtract 200 from both sides
10x
175
