Step-by-step explanation:
When f(x) = f(x - 4), 3x² = 3(x - 4)².
=> x² = (x - 4)², x = -(x - 4), 2x = 4, x = 2.
The x-value is 2.
Answer:
bought is 3/5 of the number of red balloons. The number of green balloons is also 2/3 of the number of yellow balloons.
Answer: blank 1: 26 blanks 2: 2
Step-by-step explanation:
If you divide 39 by 6 you get 6.5 which is how many cups is in each pizza. Now you multiply 6.5 times 4 and you get 26. Now you take 13 and divide it by 6.5 and get 2.
You have to distribute 3x+1 over the other parentheses
3x(2x^2 +4x-3) + 1• ( 2x^2 +4x-3)=
6x^3 +12x^2 -9x + 2x^2 +4x-3 =
Combine like terms
6x^3 +14x^2 -5x -3
