Answer:
fg(-2)=f(5×-2+4)=f(-6)=8-10×-6=8+60=68
Answer:
D
Step-by-step explanation:
The thing that is being cubed here is the sum of x and 4, not x or 4 individually. After you have taken care of what is in parentheses, you add 3x, which gives the sum of x+4 cubed and 3x. Hope this helps!
Combine like terms by adding their FACES (Coefficients)
1) 4c² - 4
2) 20m^4 + 6m
3) -6a³ - 19a² + 8a - 10
4) -10a² - 2b + 3ab³ + 4a²b² -5b^4 - 9a²b² - 12a³b + 15ab³ = -10a² - 2b + 18ab³ - 5a²b² - 12a³b - 5b^4
5) 5a³ - 5a²
Answer:
The maximum number of vases that the dance committee can buy is 
Step-by-step explanation:
Let
x------> the number of vases
we know that

Solve for x



The maximum number of vases that the dance committee can buy is 
X^2 + y^2 - 2x + 8y - 47 = 0
x^2 + y^2 - 2x + 8y = 47
(x^2 - 2x) + (y^2 + 8y) = 47
(x^2 - 2(1)x) + (y^2 + 2(4)y) = 47
(x^2 - 2(1)x + 1^2) + (y^2 + 2(4)y + 4^2) = 47 + 1^2 + 4^2
(x - 1)^2 + (y + 4)^2 = 64 = 8^2
