Answer:
x = -7, x = 9
Step-by-step explanation:
We presume your equation is ...
x² -2x -63 = 0
Factors of -63 that have a sum of -2 are -9 and +7. Then the factored equation is ...
(x -9)(x +7) = 0
Solutions make the factors zero.
x -9 = 0 ⇒ x = 9
x +7 = 0 ⇒ x = -7
The solutions to the quadratic equation are x = -7 and x = 9.
The answer to the question is 8
False, it would end up being st / r
Answer:
<h2><u><em>
D</em></u></h2>
Step-by-step explanation:
You can first reduce this fraction by dividing both the numerator and denominator by the Greatest Common Factor of 549 and 999. I know that
61/111
is the same as
61÷111
Then using
Long Division for 61 divided by 111
and rounding to a Max of 4 Decimal Places gives me
=0.5495/.5495
<h3>then move the decimal point a digit to the <u><em>
RIGHT!!!!</em></u></h3>
