What is the value of a?

Mathematics
1 answer:
Sindrei [870]2 years ago
6 0

Answer:

a=2

Step-by-step explanation:

Firstly, in order to simplify the expression, we should aim to combine the two terms given. In order to do this, both must have the same denominator. We can give them the same denominator by multiplying the second term -\frac{2}{x+2} by \frac{x+2}{x+2}. This way the fraction value remains the same but now has the same denominator as the first term:

-\frac{2}{x+2} *\frac{x+2}{x+2} \\\\=\frac{(-2)(x+2)}{(x+2)(x+2)} \\\\=\frac{-2x-4}{(x+2)^{2}}

From here we can now combine the two terms:

\frac{2x+6}{(x+2)^{2}} +\frac{-2x-4}{(x+2)^{2}} \\\\= \frac{(2x+6)+(-2x-4)}{(x+2)^{2}} \\\\\\=\frac{2x+6-2x-4}{(x+2)^{2}}\\\\= \frac{2}{(x+2)^{2}}

Therefore, a = 2.

Hope this helped!

24 x 12 1/2 x 12 3/4 what is the volume of the fish tank
hjlf

Answer:

The volume is 3825 cubic units

Step-by-step explanation:

To find the volume of the fish tank multiply out the dimensions.

We were given the dimensions as:

24 \times 12 \frac{1}{2}  \times 12 \frac{3}{4}

Change the numbers to improper fractions

24 \times  \frac{25}{2}  \times \frac{51}{4}

We cancel out to get

3 \times 25 \times 51

3825

here are five rods a-1 a a a a+3 all measurements are in cm the total length of the five rods is l cm find a formula for l in te
Elenna [48]

Answer:

I=5a+2 (simplified form)


Step-by-step explanation:

I is the total length of all the 5 rods.

Each of the 5 parts lengths are (a-1), a, a, a, (a+3), respectively.


<em>We add all of them and equate it to I:</em>

I=(a-1)+a+a+a+(a+3)

<em>Simplifying this, we take like terms and add:</em>

<em>I=(a-1)+a+a+a+(a+3)\\I=5a-1+3\\I=5a+2</em>
