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.

I already answered this but I just want to make sure if I did it right

galben [10]

$\bf \left( \cfrac{2}{3} \right)^3\cdot \left( \cfrac{3}{5} \right)^3\implies \cfrac{2^3}{\underline{3^3}}\cdot \cfrac{\underline{3^3}}{5^3}\implies \cfrac{2^3}{5^3}\implies \cfrac{8}{125}$

A store sells ladders. • The retail price was a 40 percent markup over the manufacturer price. • A month later, the store reduce

TEA [102]

For this item, we represent the very original value or price of the given item by x such that increasing the retail price by 40 percent will give us 1.4x. Also, when the retail price of the item is reduced by 25 percent, we have.
new retail price = 1.4x (1 - 0.25) = 1.05x.
This means that the new retail price is only 5% over the manufacturer price.
