Answer 1

which of the following is a like term of 7xy

Answer 2

Answer:

1. The given term is 7xy.

Hence, the correct answer is Option D i.e. 7xy.

2. A binomial expression is a mathematical expression with only two terms.

Option C i.e. x+y contains only two terms.

Hence, the correct answer is Option C i.e. x+y.

3. Given polynomials are ab + ac and ab - ac.

Adding the two polynomials

= ab + ac + ab - ac

= 2ab

Hence, the correct answer is Option A i.e. 2ab.

4. (x - y - z) - (x - y + z)

= x - y - z - x + y - z

= -2z

Hence, the answer is -2z.

5. Given terms are m, n and p.

Hence, their product will be mxnxp.

Hence Option A i.e. m*n*p is correct.

6. Given terms are -xy and yx.

Hence, their sum will be

xy + (-xy) = 0

Hence, Option B i.e. 0 is correct.
