The lengths of three sides of a quadrilateral are shown below: Side 1: 3y2 + 2y − 6

Side 2: 3y − 7 + 4y2

Side 3: −8 + 5y2 + 4y

The perimeter of the quadrilateral is 4y3 + 18y2 + 16y − 26.

Part A: What is the total length of sides 1, 2, and 3 of the quadrilateral?

Part B: What is the length of the fourth side of the quadrilateral?

Part C: Do the answers for Part A and Part B show that the polynomials are closed under addition and subtraction? Justify your answer.

this is not the answer this is just a question. is this middle school math?

step-by-step explanation:

omg what happend to your question? if you could edit this question i can

step-by-step explanation:

correct answer is option b.

step-by-step explanation:

the true statement about geometric figure is option b that is one line can be drawn through all three points.

if three points are on the same plane, they can be connected by a line.

the arc length is found by finding the circumference of the full circle (2xpixradius) and then dividing by 4 to find just one quarter of the circle (90 degrees).
