Answer:
Give me more fees back on your equation
Step-by-step explanation:
Evaluate A² for A = -3.
(-3)² = (-3) * (-3) = 9
Your answer is 9.
If the question is, however, evaluate A2, which is 2A, for A = -3, then the answer is:
2A = 2(-3) = -6.
Answer: -a^2+c\left(a-c\right)-n^2a=3\quad :\quad c=-\frac{-a+\sqrt{-3a^2-4an^2-12}}{2},\:c=-\frac{-a-\sqrt{-3a^2-4an^2-12}}{2}

Answer:
$10
Step-by-step explanation:
The price of the item before tax is 100% of its price since 100% means the entire thing.
When you add a 15% tax, the total price (including tax) is now 115% of the original price.
The original price is unknown, so we call it x.
115% of x is $11.50
115% * x = 11.50
1.15x = 11.5
x = 10
