8 0

Answer:

= - x^2 + 4x  - 14

Step-by-step explanation:

(2x^2+6x−7)−(3x^2+3x−1)+(x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   (x−8)​

= (2x^2+6x−7   )    −3x^2   -3x  +1     +   x−8​

= (2x^2+6x−7   )    −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= 2x^2+6x−7       −3x^2   -2x - 7

= - x^2 + 4x  - 14

Which expression is equivalent to One-fifth (150 x minus 80 y + 50 minus 50 x minus 25 y + 20)?
inna [77]

Answer:

The answer to your question is  20x + 21y + 14        

Step-by-step explanation:

Data

Expression             1/5 (150x - 80y + 50 - 50x - 25y + 20)

Process

1.- Multiply 1/5 by each term

                                     150/5x - 80/5y + 50/5 - 50/5x - 25/5y + 20/5

2.- Simplify

                                      30x - 16y + 10 - 10x - 5y + 4

3.- Simplify like terms

                                      (30x - 10x) + (-16y - 5y) + (10 + 4)

4.- Result

                                        20x + 21y + 14

You are most likely to encounter an irrational numbers when you’re
MArishka [77]

Answer:

Taking square-root of numbers

Step-by-step explanation:

The reason is that the square-root of most numbers is an irrational number because the answer we have can not be written as p/q form. For example, if we take the example of √2 then the answer we have is "1.4142135623730950..." which can not be written in p/q form. Hence taking square-root of numbers will most likely give an irrational number.
