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

Solve the inequality<br> 7+7(x+4)&gt;21
Kryger [21]

Answer:

x>-2

Step-by-step explanation:

Hi there!

We are given the inequality 7+7(x+4)>21, and we want to solve it

Solving an inequality is a lot like solving an equation; we want to isolate x on one side by itself.

So to start, we'll preform the distributive property on 7(x+4) (multiply x by 7, then multiply 4 by 7 and add those two together).

7+7x+28>21

Now combine like terms.

7x+35>21

Subtract 35 from both sides

7x>-14

Divide both sides by 7

x>-2

Hope this helps!
