option 2 and 6

Step-by-step explanation:

## Video explanation

Given : Monomial To find : Adding which terms to would result in a monomial? Check all that apply.

Solution :

Monomial is when the number of terms is only 1.

Therefore, Option 2 and 6 are the terms giving a monomial.

### Faq

Mathematics Step-by-step explanation:

Given monomial: , here deg of x is 2 and deg of y is 1

From the options, we have polynomials [with deg of x is 2 and deg of y is 1]which are like to the given polynomial.

We know that if we add like monomials, then we get result as mnomila.

Rest of other monomials are unlike to the given monomial, which will result into  binomial. Mathematics

Adding which terms to 3x2y would result in a monomial? Check all that apply.

3xy

–12x2y

2x2y2

7xy2

–10x2

4x2y

3x3

Step-by-step explanation: correct answers are b) -12x2y and f) 4x2y

Mathematics

By adding 12x²y and 4x²y result will be a monomial.

Step-by-step explanation:

Given question is incomplete; here is the complete question.

Adding which terms to 3x²y would result in a monomial? Check all that apply.

3xy

–12x2y

2x2y2

7xy2

–10x2

4x2y

3x3

1). 3x²y + 3xy → [Binomial]

2). 3x²y - 12x²y = -9x²y → [Monomial]

3). 3x²y + 2x²y²  → [Binomial]

4). 3x²y + 7xy² → [Binomial]

5). 3x²y - 10x² → [Binomial]

6). 3x²y + 4x²y = 7x²y → [Monomial]

7). 3x²y + 3x³ → [Binomial]

Therefore, by adding 12x²y and 4x²y result will be a monomial.

Mathematics
Only the terms containing the variables x²y are "like" terms:
-12x²y
4x²y
Mathematics
Adding and subtracting a monomial requires having the same variables. No matter how big or small their coefficient is, if their variables do not match, they cannot be added or subtracted. The crucial part in adding or subtracting monomials is their sign. If the signs are the same, retain the sign. If the signs are different, subtract and keep the sign of the larger number.

3x2y + 3xy (cannot be added)
3x2y + (–12x2y) = -9x2y
3x2y + 2x2y2 (cannot be added)
3x2y + 7xy2 (cannot be added)
3x2y + (–10x2) (cannot be added)
3x2y + 4x2y = 7x2y
3x2y + 3x3 (cannot be added)

%Error=(|True-Measured| / True)*100

Here,

True=3 hours

Measured=5 hours

|True-Measured|=|5-3|=2

%Error=2/3*100
