A circular table has a diameter of 20 inches.what is the area of the table
Effectus [21]
Hello!

To find the area of a circle you do \pi r ^{2}

the "r" stands for radius which is half the diameter

So we do \pi * 10^{2}

Which gives us the answer of 314.16

Hope this helps!

Solve using the lcd:<br> 1/x = 1/5 + 5/4x
Black_prince [1.1K]

The value is x= -5/4

<h3>What is LCD?</h3>

The least common denominator is the smallest number of all the common multiples of the denominators when 2 or more fractions are given.

Given:

1/x = 1/5+ 5/4x

1/x = 4x + 25 / 20x

20= 4x +25

4x= -5

x= -5/4

Pls help in a middle of an exam
KIM [24]

Answer:

\frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}

Step-by-step explanation:

\frac{2x}{4x^2-9} + \frac{3}{2x^2+x-3} can be simplified to:
\frac{2x}{(2x-3)(2x+3)}+\frac{3}{(2x+3)(x-1)}

Make them have common denominators so:
\frac{(2x)(x-1) +3(2x-3)}{(2x-3)(2x+3)(x-1)}

Simplify:
\frac{2x^2-2x+6x-9}{(2x-3)(2x+3)(x-1)} = \frac{2x^2+4x-9}{(2x-3)(2x+3)(x-1)}

I don't think you can simplify that fraction further so that's the answer.
