Which expression can you simplify by combining like terms?

omeli [17]

Answer:

The correct option is A.

Step-by-step explanation:

If the degree and variables of two terms are same, then they are called like terms.

In option A.

The given expression is

$12b^2+4ab-3ba-6$

Here, 4ab and -3ab are like terms because both have same variables a and b with degree 1.

By combining like terms we get

$12b^2+(4ab-3ab)-6$

$12b^2+ab-6$

In options B, C and D, there are no like terms, So only the expression $12b^2+4ab-3ba-6$ we can simplify by combining like terms.

Therefore the correct option is A.

2 missing number=38

Step-by-step explanation:

1 45+55+76+y+88+54/6

316+y/6=63.6

316+x381.6

x=381.6-316=65.6

2M4 =63

60-62+92+x/4=63

214+x=252

x=252-214

Doss [256]

Answer:

$5565$

Step-by-step explanation:

$1+2+3+4...+113+114=\frac{114*115}{2} =6555$

$1+2+3+4 ... +43+44=\frac{44*45}{2} =990$

Thus, $45+46+47+48...+113+114=$ $6555-990=5565$
