Answer:

Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is 14

Step-by-step explanation:

The question given is:

Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is?

First we will Subtracting 3x^2+4x-5 from 7x^2+x+9

7x^2+x+9-(3x^2+4x-5)\\=7x^2+x+9-3x^2-4x+5\\Combining\:like\:terms\\=7x^2-3x^2+x-4x+9+5\\=4x^2-3x+14

So, the polynomial we get is: 4x^2-3x+14

Now, subtracting 4x^2-3x\: from\: 4x^2-3x+14

4x^2-3x+14-(4x^2-3x) \\=4x^2-3x+14-4x^2+3x\\Combining\:like\:terms\\=4x^2-4x^2-3x+3x+14\\=14

The difference is 14

So, Subtracting 3x^2+4x-5 from 7x^2+x+9 results in a polynomial. After subtracting 4x^2-3x from this polynomial the difference is 14

2) 1/10


<u>Experience</u>

There are infinate fractions between any two integers. The same way there are somany numbers between 0.08 and 0.4.

Examples are 0.09, 0.10, 0.11. 0.12,0.2,0.3, 0.35 and many more.

I will just pick two of them and write them as a fraction.

1) 0.11 = 11/100

2) 0.20 = 20/200

             = 2/20

             = 1/10
