Answer: x = 7/2 and 3

Step-by-step explanation: Rewrite and factor

2x² —13x + 21 = 0

(2x - 7)(x - 3) = 0

2x - 7 = 0. x = 7/2

x - 3 = 0 x = 3

Find the equation of the line of symmetry of y= (x+2)(x-8).​
Daniel [21]

Answer:

line of symmetry , x = 3

Step-by-step explanation:

Standard form of quadratic equation  is y = ax^2 + bx + c, where a, b, and c equal all real numbers. You can use the formula x = -b / 2a to find the line of symmetry.

y = (x+ 2)(x-8)\\\\y = (x^2 -8x + 2x -16)\\\\y = x^2 -6x -16

a = 1, b = -6, c = -16

Line of symmetry is ,

                           x = -\frac{b}{2a} = -\frac{-6}{2}  = 3

Answer:

54 sq units

Step-by-step explanation:

The triangle at the top (FAB) has a base of 10 and a height of 3. Area of triangle is 1/2bh so 1/2(10 * 3) = 1/2 * 30 = 15 sq units

If you cut off the triangle you have a trapezoid, EBCD. A trapezoid is (b1 + b2)/2 * h, so (6 + 7)/2 * 6 = 13/2 * 6 = 6.5 * 6 = 39 sq units

Add them together: 15 + 39 = 54 sq units
