Answer:
100 pi
Step-by-step explanation:
you do
4pi x 5 squared
This is very similar to solving linear equations except for one thing, If we multiply or divide by a negative number, we must flip the inequality sign.
<h3>What is linear inequality?</h3>
In mathematics, inequality occurs when a non-equal comparison is made between two mathematical expressions or two numbers. In general, inequalities can be either numerical inequality or algebraic inequality or a combination of both.
To better understand it, let's examine the example.
2x - 5 < 3
So, when we solve, let's just consider the inequality sign like a regular equal sign.
Let's start by adding 5 to each sides.
2x - 5 + 5 < 3 + 5
To find the value of x , we must divide it by two.
2x/2 <8/2
And the final result is x= 4.
This is our answer.
So if we need to graph it, let’s draw a number line and draw an open circle at 4. Open circle because x is not equal to 4. Then make an arrow going to the left.

Answer:
1. (x+8)(x-4)
2. 3x-20
Step-by-step explanation:
1. x² + 4x – 32
x² + 8x - 4x - 32
x (x+8) - 4 (x+8)
one of the x+8's is cancelled out then you have (x+8)(x-4)
2. x2 + x - 20
2x+x-20
3x-20
