x is 12 as 2 plus 10 so that you can write the value or tell the value
Answer:
x = ± 15
Step-by-step explanation:
Given f(x) = - 0.5x² and f(x) = - 112.5 , then equate right sides
- 0.5x² = - 112.5 ( divide both sides by - 0.5 )
x² = 225 ( take square root of both sides )
x = ±
= ± 15

There are infinite fractions with common factor of 8, any fraction in the form

where k and n are coprime, can be simplified to

by simplifying the common factor of 8.
Answer:
-8/3 or -2.66666 or -2 2/3
Step-by-step explanation:
Move constant (+9) to the right side and change its sign (25 - 9)
Then subtract those numbers (=16)
