Answer:
Step-by-step explanation:
y = -3x² + 24x - 50
factor out leading coefficient
y = -3(x² - 8x) - 50
complete the square
coefficient of the x term: -8
divide it in half: -4
square it: (-4)² = 4²
use 4² to complete the square and keep the equation balanced:
y = -3(x² - 8x + 4²) + 3(4²) - 50
y = -3(x-4)² - 2
Yes, Lynn does have enough for each classmate in class, If she wants to give each kid 1/4 of a candy bar, 4(the amount of kids that can get candy per bar) x8(candy bars) would equal 32.
Answer:
The answer to your question is: 4a² + 4b² + 8ab
Step-by-step explanation:
Simplify 4(a² + b² + 2ab)
The only step is to multiply 4 by each term
4a² + 4b² + 8ab
314,000,000/7100000000= .0442253521
So approximately 4% of the world population is in the U.S
