A) f(x+1) = 6x^2 + 8x + 6
1) substitute the value of x as (x+1)
2) 2(3(x+1)^2 -2(x+1) +2)
3) 6(x^2 + 2x + 1)
4) 6x^2 + 8x + 6
B) f(3) = 46
1) simplify the expression first
2) 6x^2 -4x + 4
3) Now just substitute 3: 6(3)^2 -4(3) + 4
4) 6•9 - 12 + 4 = 46
I hope this helps :)
Don't really know how to explain it, but here's an example on how to factor out the coefficient of the variable, hope this explains it!
Factoring out the coeffecient of a variable:
Example:
9x-36
How to factor the coeffecient of the variable: Would then get 9(x-36)
Another example:
1/5k+15
Answer: (1/5)(k+15)
Answer:
6x - 9y = -12
Step-by-step explanation:
2x - 3y = -4 multiply both sides by 3 by adding paranthesis to represent this
3( 2x - 3y ) = 3 (-4) Then use distributive property for the left side equation
6x - 9y = -12 Finally just multiply -4 by 3 and you get this equation
Answer: True, angles that are congruent are equaled to each other
