Answer:
4th grade questions?
I can easily help you with those.
What are your questions?
X=7 because 7+6=13 and 3•13=39
The "center" is that of the point?
Lets solve the quadratic equation:
<span>7x^2 + 2x = 0
(x)(7x + 2) = 0
therefore, for this equation to hold we need, either one of these conditions:
x = 0
or
7x + 2 = 0
from where:
7x = -2
x = -2/7
then, we have two solutions for the equation as expected being quadratic.</span>
Step-by-step explanation:
The angle is 13.134 degree
I Hope this is right and help for you
