D. B,C,A

Step-by-step explanation:

A= |7|=7

B= -6

I got 70

Combination=n!/((n-r)!r!)

=8!/((8-4)!*4!)

=8*7*6*5*4!/(4!*4!)

=8*7*6*5/(4*3*2)

For the diagram at right, write and solve an equation to find x

Tomtit [17]

Answer:

x = 24

Step-by-step explanation:

The formula for determining the sum of interior angles is:

$(n-2) * 180$

$4 * 180 = 720$

Therefore to determine an equation for x, we must add up all the interior angle equations and set them equal to 720.

$(2x+3) +(3x+12) + (7x+14) + (9x+2) + (4x+8) + (3x+9) = 720\\28x + 48 = 720\\28x = 672\\x = 24$

The equation and answer above shows how to find x, which equals 24.
