100 POINTS IM LITERALLY BEGGING. this is due tomorrow and im already failing so this would help so please if you do it, do it right. and i posted this twice so when you do this one answer the other on my account for 50 more points. PLEASE

answer:

Step-by-step explanation:

1.(27-2)×180=25×180=4500° ,B

2. (n-2)×180=2340

n-2=2340/180=13

n=15

3. 10x-3+5x+2+7x-11+13x-31+8x-19=(5-2)×180

43x-62=540

43 x=540+62=602

x=14

m∠ S=13x-31=13×14-31=182-31=151°

4. 6(11x+21)=(6-2)×180=720

11x+21=720/6=120

11 x=120-21=99

x=9

5.x=360/9=40°

6.7x-2+9x-31+4x+33=360

20x=360

x=18

m∠DCE=180-(7x-2)=180-(7×18-2)=180-(126-2)=180-124=56°

7. (n-2)180/n=168

180(n-2)=168 n

180n-360=168 n

180 n-168 n=360

12 n=360

n=360/12=30 sides B

8. A

9. Rectangles

squares

iscosceles Trapezoids.

answer: you need the equation in the question so i can answer it

step-by-step explanation:

(0,,,0)

step-by-step explanation:

the table of x and y values is shown in the attached pic(part of question)

we have to decide according that graph

given points are (0, 0) (–1, 0), (2, 0)

when we graph these points on graph they show an increasing line as shown in the attached pic
