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.

$\dfrac{\frac{5\pi}{12}}{2\pi}=\dfrac{5}{24}$

$\text{therefore the arc is equal} \dfrac{5}{24}\ \text{of circumference of a circle}.$

$\text{The formula of a circumference of a circle:}\ C=2\pi r$

$\text{substitute}\\\\\dfrac{5}{24}\cdot2\pi r=4\\\\\dfrac{5}{12}\cdot3.14r=4\\\\\dfrac{15.7}{12}r=4\ \ \ \ |cdot\dfrac{12}{15.7}\\\\r\approx3.1\ in$

$Answer:\ 3.1\ in$
