Mathematics

Answer:

The x-intercepts are (-2,0)  and (-3, 0).

Step-by-step explanation:

To find the x intercept(s) we solve this equation for x:

x^2 + 5x + 6 = 0

(x + 3)(x + 2) = 0

x + 3 = 0 gives x = -3

and x+ 2 = 0 gives x = -2.

Answer:

A  = 222 units^2

Step-by-step explanation:

To find the area of this trapezoid, first draw an imaginary horizontal line parallel to AD and connecting C with AB  (Call this point E).  Below this line we have the triangle CEB with hypotenuse 13 units and vertical side (21 - 16) units, or 5 units.  Then the width of the entire figure shown can be obtainied using the Pythagorean Theorem:

(5 units)^2 + CE^2 = (13 units)^2, or 25 + CE^2 = 169. Solving this for CE, we get |CE| = 12.

The area of this trapezoid is

A = (average vertical length)(width), which here is:

       (21 + 16) units

A  = --------------------- * (12 units),   which simplifies to:

                  2

A = (37/2 units)(12 units)  =  A  = 37*6 units  =  A  = 222 units^2
