A=60 degree same
60-60-60
Answer:
3a³ - 6a² - 2
Step-by-step explanation:
X²Y - Z
= a²(3a - 5) - (a² + 2) ← distribute both parenthesis
= 3a³ - 5a² - a² - 2 ← collect like terms
= 3a³ - 6a² - 2
Well, since she bought 3.42 pounds of green apples, then you can subtract 3 lbs off of that, so she bought .42 lbs of green apples, and 2.19 lbs red apples
So now, you just need to add .42 and 2.19
.42 + 2.19 = 2.61, so she has 2.61 lbs of apples left
Hope this helped!

Answer:
1/8.
Step-by-step explanation:
Use l'Hopitals rule - we find the derivative of top and bottom of the fraction.
Derivative of the numerator = 0 - 1/2 (16 - x)^-1/2 -1
= 1 / [ 2 * (16 - x)^1/2
Derivative of the denominator = 1
When x approaches 0 this is 1 / (2*4)
= 1/8.
Another way to do this is to multiply top and bottom by 4 + (16 - x)^1/2
This becomes 16 - (16 - x) / x(4 + (16-x)^1/2)
= 1 / (4 + (16 + x)^1/2
When x ---> 0
this = 1 /(4 + 4)
= 1/8.
