Answer:
Trapezoid
Step-by-step explanation:
We have been given that Marcus drew a quadrilateral with only 1 pair of parallel sides. We are asked to determine the quadrilateral that Marcus drew.
We know that a parallelogram has two pair of parallel sides. 
We also know that rhombus is a parallelogram whose 4 sides are equal is measure and rectangle is a parallelogram with opposite sides equal. 
Since parallelogram, rhombus and rectangle has two pair of parallel sides, therefore, Marcus didn't draw any of these.
We know that trapezoid has only one pair of parallel sides, therefore, Marcus drew a trapezoid.
 
        
             
        
        
        
Answer: Y=-1 or Y=-1+4
Step-by-step explanation:
<h3>Use the formula y2- y1 over x2-x1 so it should look like this 1-3 over 3-1 which is -2 over 2 then you divide that which is -1 and if you have to find one all you have to do is use one point label which is x and y so I pick (1,3) so you put 3=-1(1) once you have that you multipy so -1 times 1 is -1 so your gonna add 1 to the -1 and the three the -1 cancel out because it is a zero pair 3+1 is 4 so B=4 </h3>
 
        
             
        
        
        
Answer: x^2 - 14x + 49
Explanation:
1) Divide the coefficient of x by 2:
14 / 2 = 7
2) so you have to add 7^2 = 49
x^2 - 14x + 49
3) that trinomial is equivalent to:
=> (x - 7)^2 
4) prove that using the formula (a - b)^2 = a^2 - 2ab + b^2
(x - 7)^2  = x^2 - 14x + 49
Then you have to add 49 to complete the square. and form a perfect square trinomial.
