There is 33 students in the class
Answer:
fourth option
Step-by-step explanation:
Given
3x < - 9 ( divide both sides by 3 )
x < - 3
solution set is { x | x < - 3 }
The factored form of the expression 
is 
The expression x^2 + 9 has no real roots hence cannot be factored
Quadratic equations are equations with a degree of 2.
Given the quadratic function 
For the function
Using the difference of two squares:
For the expression x^2 + 9
The expression x^2 + 9 has no real roots hence cannot be factored

A parallelogram is a quadrilateral with opposite sides parallel. The first figure above is a parallelogram. ... A rectangle is a quadrilateral because it has four sides, and it is a parallelogram because it has two pairs of parallel, congruent sides. All four angles are right angles.
Show me the picture of the octagon. But remember that if the diameter is shown than always do half of the diameter to get the radius. Hope this helps
