Answer:
g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
Step-by-step explanation:
<u>Given, function:</u>
<u>For the domain x= (a+b), the g(x) is:</u>
- g(a+b) = 3*(a+b)² - 2(a+b) - 1 = 3a² + 3b² - 6ab - 2a - 2b - 1
- g(a+b) = 3a² + 3b² - 6ab - 2a - 2b - 1
Answer:
C
Step-by-step explanation:
This is a linear equation in one variable and has 1 solution
12x + 6 = 5x ( subtract 5x from both sides )
7x + 6 = 0 ( subtract 6 from both sides )
7x = - 6 ( divide both sides by 7 )
x = -
← 1 solution
A-$70 is the correct answer, even though im not sure.
