Ummmm I think so yeah haha
My name is London I need help for a math test I’m very bad in math I’m only in the 6th grade middle school basically
Holly has 20 balls, and there are 100 balls in total.
So there are 100-20 = 80 balls left.
Alex had 2 * the amount Holly had, which is 20.
So Alex has 20 * 2 = 40 balls.
Together, they have 60 balls.
Which means 100-60 = 40. So Ben has 40 balls.
Check:
Holly: 20
Alex: 40
Ben: 40
Add them: 20 + 40 + 40 = 100
Answer:
(0.353, -48)
Step-by-step explanation:
dy/dx = 9x² + 28x - 11 = 0
Using the quadratic formula:
x = -3.46 and 0.353
d²y/dx² = 18x + 28
Minima when d²y/dx² is positive
x = 0.35284 or (-14+sqrt(295))/9
y = 3x³ + 14x² - 11x - 46
y = -48.00651351
