PLZ HELP 100 PTS!!!!!!!!!!!!!!!!!
erma4kov [3.2K]

Answer:

x = 12

Step-by-step explanation:

The mistake made here is in making 130 = 9x + 7. They are not the same.

The central angle = 130 degrees.

Any angle sharing the endpoints of the central angle and having it's vertex on the same side of the central angle is 1/2 the central angle.

1/2 the central angle = 130 /2 = 65

Cyclic quadrilaterals (those with all 4 points touching a circle's circumference) have opposite angles  supplementary.

65 + 9x + 7 = 180           Combine like terms on the left

72 + 9x = 180                 Subtract 72 from both sides

72 - 72 + 9x = 180-72     Combine

9x = 108                          Divide by 9

9x/9 = 108/9                  

x = 12

16x² +8-7x-3x2 - 13x
liq [111]

Answer:

13x^{2}-20x+8

Step-by-step explanation:

Step 1: rearrange the equation

16x^2 - 3x^2 - 7x - 13x +8

Step 2: solve the equation

16x^2 - 3x^2 = 13x^2

-7x - 13x = -20x

(the +8 will stay the same)

so when we put it all together it gives us

13x^2 - 20x + 8
