Answer:

x^2-8x-9

x

2

−8x−9

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10)

Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get  , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together:  . Then combine like terms

Find the value of x. Then find the angle measures of the polygon.
Bess [88]

Question 11

x+x+1/2x+1/2x=360

x+x+2/2x+=360

x+x+x=360

3x=360

x=120

Then substitute 120 in the place of x

x1=120

x2=120

1/2(120)=60

1/2(120)=60

To check your answer you can add 60+60+120+120 the should be equal to 360

Question 12

x+x+(x-45)+(x-45)+(x-45)=540

x+x+x-45+x-45+x-45=540

5x-135=540

5x=540+135

5x=675

x=675/5

x=135

Then substitute 135 in the place of x

x1=135

x2=135

135-45=90

135-45=90

135-45=90

To check your answer you can add 135+135+90+90-90 the should be equal to 540
