Which of the binomials below is a factor or this trinomial x-2 +5x+6

lutik1710 [3]

Firstly, for it to be a trinomial the expression would have to be x^2+5x+6 to factor this we would simply have to find 2 numbers that add up to 5 and multiply to 6. 3+2=5 and 3•2=6 so (x+3)(x+2) would be the answer

Of 734 students, 442 are taking mathematics. What angle (in degrees) of a circle would show the percent of students taking mathe

Anestetic [448]

We need to find the angle (rounded to the nearest whole degree) of a circle that would represent the percent of students taking mathematics.

Since a complete turn around the circle has 360º, we have the following proportion:

<em>Number of students Angle</em>

734 360º

442 x

Then, cross multiplying the above values, we obtain:

$\begin{gathered} 734x=442\cdot360\degree \\ \\ x=\frac{442\cdot360\degree}{734} \\ \\ x\cong217\degree \end{gathered}$

<em>Answer</em>: 217º
