4 0

Answer:

QS ≈ 4.71 units

Step-by-step explanation:

The arc QS is calculated as

QS = circumference of circle × fraction of circle

     = 2πr × \frac{90}{360} ( r is the radius )

     = 2π × 3 × \frac{1}{4}

     = 6π × 0.25 ≈ 4.71 units ( to the nearest hundredth )

Choose whether the expression is a result of multiplying
vladimir1956 [14]

Answer:

neither

Step-by-step explanation:

Take out 5 as a common factor. It will be easier to look at.

5(5c^2 + 11c + 6)

5(5C +6 )(c + 1 )

Now you can put the 5 inside.

(25c + 30)(c + 1) is one answer.

(5c + 6)(5c + 5) is another.

The answer is multiplying binomials. There is nothing that that is squared and the answers are not conjugates. They are two binomials multiplied together.
