2x^2 / x^2 - y^2 - x^2 / xy - y ^ 2​

Mathematics
1 answer:
Juliette [100K]3 years ago
6 0

Answer:

2 - 2y^2 - x/y

Step-by-step explanation:

2x^2/x^2 = 2

and

x^2/xy = x/y

therefore

2x^2/x^2 - y^2 - x^2/xy - y^2

= 2 - y^2 - x/y - y^2

= 2 - y^2 - y^2 - x/y

= 2 - 2y^2 - x/y

Advocard [28]

Answer:

C

Step-by-step explanation:

(f + g)(x) = f(x) + g(x) , thus

f(x) + g(x)

= 2x + 1 + x² - 7 ← collect like terms

= x² + 2x - 6 → C

Petra eats five and three fifths pies in a pie-eating contest. Paulie eats three and fourteen sixteenths pies in the contest. Ho
Alex777 [14]

Answer:

2 7/20

Step-by-step explanation:

So Lets put these into a fraction form

Petra: 5 3/5

Pauline: 3 4/16 -> Can be Simplified = 3 1/4

Take the number of pies Petra Ate and subtract it by the number of pies Pauline ate

Change the numbers to a common factor. (multiply 3/5 by 4 and 1/4 by 5 to have common denominators)

5 \frac{12}{20} - 3 \frac{5}{20}

Make These Into a Mixed Fraction

\frac{112}{20} -\frac{65}{20}

Subtract 112-65

\frac{47}{20}

Simplify (divide 47 into 20 how many times to get into a mixed fraction)

2 \frac{7}{20}

I think this is right. Hope This Helps
