If you would like to solve the inequation X - 9 > 6, you can calculate this using the following steps:
X - 9 > 6 /+9
X - 9 + 9 > 6 + 9
X + 0 > 15
X > 15
The correct result would be X > 15.
3/5 / 3/7
= 3/5 * 7/3
= 7/5 or 1 2/7
Answer:
What does it say.
I can't see the photo at all !
Step-by-step explanation:
So, x^2 + 14 x + 49 - 4 = 0;
Then, we use the formula ( a + b )^2 = a^2 + 2ab + b^2;
We have ( x + 7 )^2 - 2^2 = 0;
Then, ( x + 7 )^2 - 2^2 = 0;
We use the formula a^2 - b^2 = ( a - b)( a + b );
We obtain ( x + 5 )( x + 9) = 0;
Then, x + 5 = 0;
x = -5;
x + 9 = 0;
x = - 9;
-5 and - 9 are the zeros of the quadratic function.
