Given 4x-1=3x+3
First, get x on one side.
Do this by adding 1 to both sides.
4x-1+1=3x+3+1
You get: 4x=3x+3
Subtract 3x from both sides: x=3.

<span>Given:
formula for the slant height of a cone is I= s-π(pie)r^2 over π(pie)
where S is surface area of the cone
S(surface area) = 500π ft^2
r(radius) = 15 ft
Required:
l in m
Solution:
</span>I = (s - πr²) / π
I = (500π - π(15)²) / π
l = 275 ft (1m / 3.2808 ft)
l = 83.82 m
The quadratic formula is:

and

Let's identify our a, b, and c values:
a: -1
b: 1
c: 12
Plug in the values for a, b, and c into the equation. Let's do the first equation:

Simplify everything in the radical:

Simplify the radical:

Combine like terms:

Simplify:

This is one solution, now, let's solve for the other equation:
Since when simplified, everything is the same except the subtraction sign, we can skip the simplification again and change the sign to subtraction:

Combine like terms:

Simplify:

Your final answers are:
