Step-by-step explanation:
Plug in every scenario, in see if it equal to each other.
D is the only one that is equal.
Answer:
<h3>$825 it would be that</h3>
Step-by-step explanation:
<h3>it would be that all you have to do is multiple 55×15=825</h3><h3>5×5</h3><h3>
</h3>
1. B is 4 and c is 8
2. A and b are 5square root of 2
4. B is 7 and c is 14
5. A and b is 6 square root of 2
Because of the relatively large coefficients {9, 42, 49}, applying the quadratic formula would be a bit messy. Instead, I've chosen to "complete the square:"
9x^2 + 42x + 49 = 0 can be re-written as 9 [ x^2 + (42/9)x ] = -49
Dividing both sides by 9, we get [ x^2 + (42/9)x ] = - 49/9
Completing the square: [ x^2 + (42/9)x + (21/9)^2 - (21/9)^2 ] = -49/9
[ x + 21/9 ]^2 = 441/81 - 441/81 = 0
Then [ x + 21/9 ] = 0, and x = -21/9 (this is a double root).
