Start with <span>x^2 +14x = -24,

Find HALF the value of 14:  7
Square this:  49
Add 49, and then subtract 49:        x^2 + 14x + 49 - 49 = -24  We have a
                                                                                             perfect square
Rewrite the quadratic as the sq. of a binomial:                    trinomial on
                                                                                              the left
                                                         (x+7)^2 = 25

Take the sqrt of both sides:  x+7 = plus or minus 5

Then x = -2 and x = -12</span>

Naddik [55]

Answer:

The regular polygon that she should use is an equilateral  triangle

Step-by-step explanation:

The parameters given are;

Interior angles = 0.5 × Exterior angles

Exterior angles of a regular polygon = 360/n

Sum of interior angles of a regular polygon = (n - 2) × 180

Where n = the number of sides

Therefore, the sum of exterior angles of a regular polygon = 360°

Hence we have;

(n - 2) × 180 = 360/2 = 180

n - 2 = 180/180 = 1

n = 1 + 2 = 3 which is a three sided regular polygon or an equilateral triangle

Therefore, the regular polygon that she should use is an equilateral  triangle
