Simplify the expression 3x(x – 12x) + 3x2^ – 2(x – 2)2^. Which statements are true about the process and simplified product? Check all that apply.
• the term -2(x-2)2^ is simplified first by squaring the expression x-2.
• The simplified product is a binomial.
• after multiplying the like terms are combined by adding and subtracting.
•The parentheses are eliminated through multiplication.
• The final simplified product is -28x2^ + 8x - 8.

step-by-step explanation:

6x9

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

there is no answer sorry!
