Solution :

Shawndra said that it is not possible to draw a trapezoid that is a rectangle, but it is possible to draw a square that is a rectangle.

The bases of the trapezoid are parallel to each other but the sides,angles and diagonals of the trapezoid are not congruent . While the opposite sides, angles and the diagonals of  the rectangle are congruent .Therefore , it is not possible to draw a trapezoid that is a rectangle.

A square is a parallelogram whose  opposite sides are parallel and congruent, all angles are right. These properties are also found in a rectangle. Therefore,  it is possible to draw a square that is a rectangle.

Hence, Shawndra is saying correct.

What are the x-intercepts of x^2– 3x = 4?
Sindrei [870]

Answer:

x^2-3x=4

x^2-3x-4=0

x^2-4x+x-4=0

x(x-4)+1(x-4)=0

(x+1)(x-4)=0

x=-1,4

x- intercepts in the point (-1,0) and (4,0)

Find the measure of exterior angle A. Show equations and all work that leads to your answer.
Morgarella [4.7K]
Fine but I ain't showing my work completely.

The sum of all ext. angles of a polygon = 360.

So, you make this formula and solve for x.

360 = 49 + (3x+30) + (14x+6) + (6x-3) + (4x+8)
360 = 49 + 27x  + 30 + 6 -3 + 8
360 = 90 + 27x
270 = 27x
/27      /27
  10 = x

Now substitute for angle A, which is (6x-3)
6x-3
6(10)-3
60-3
57

Therefore, angle A is 57 degrees.
