Answer 1

Answer:

1)Take away 2x²-10 from x²+y². the result is

c)x²+y²-10

2)(-a)÷(-b) =

b)+a/+b

3)An algebraic expression with a single term is

c)monomial

Answer 2

Answer:

1 ) b : - x² + y² + 10

2) b: +a/+b

3) c : monomial

Step-by-step explanation:

1) [x²+y² ] - [2x²-10] = x²+y² - 2x²+ 10

= x² - 2x² + y² +10

= - x² + y² + 10

2)

$\frac{ - a}{ - b}$

we can cancel the '-' is both a and b and we get

$\frac{a}{b}$
