Answer:
87.28 cubic inches
Step-by-step explanation:
Leigh wants to fill the conical candle wax mold completely with candle wax.
We have to calculate the volume of the cone by the formula :

Here, V = volume
r = radius = 2.1 inches
h = height = 18.9 inches
By substituting these values given, into the formula

= (27.783)π
= 87.28 inch³
Conical mold can hold 87.28 inch³ candle wax.

Answer: 4^x+5x-2</h3>
Add up the equations and combine any like terms. In this case, the like terms are -8 and +6 which combine to -2. Everything else is unlike terms so you leave them as is.
f(x) + g(x) = (4^x-8) + (5x+6)
f(x) + g(x) = 4^x + 5x + (-8+6)
f(x) + g(x) = 4^x + 5x - 2
