Answer:
Where's the Answer? There's No
A good place to start for this question is to define the properties of the geometric terms you are given.
Quadrilaterals have four straight sides.
Parallelograms are quadrilaterals that have two pairs of parallel sides. The opposite sides and opposite angles are congruent. Squares, rectangles, and rhombuses are examples of parallelograms.
Trapezoids are also quadrilaterals. They have only one pair of parallel sides.
So we're looking to see if there are any four-sided shapes that can be made with no parallel sides. The attached picture shows an example of a quadrilateral that is not a parallelogram and is not a trapezoid. Based on these properties of polygons, the correct answer is B.
Answer:
a=4
Step-by-step explanation:
ax − 4 = 2y
We need to get the equation is slope intercept form y= mx+b.
Lets solve for y
Divide each side by 2
a/2 x - 4/2 = 2y/2
a/2 x -2 = y
or y=a/2 x -2
The slope is a/2 and the y intercept is -2
We want a slope of 2 so a/2 =2
a/2=2
Multiply each side by 2
a/2 * 2 =2*2
a =4
