The standard form equation for a circle is
where (h, k) is the center and r is the radius.
The standard form equation for an ellipse is
(center h, k and major and minor axes a and b)
This equation is standard form for neither, but might be general form for one.
Answer:
Expression representing number of text messages sent on Tuesday = 2x , where x = text messages sent on Monday
Step-by-step explanation:
Let number of messages sent on Monday = x
So, number if messages sent on Tuesday = 2 times x = 2x
Number of texts sent on Wednesday = 12 more than texts sent on Tuesday = 2x + 12
Number of texts sent on Thursday = Half the texts sent on Wednesday = 1/2 (2x + 12) = x + 6
Multiply the factors together. You should get the original expression.
For example, if we are to factor
2x^2 + 4x
we would factor as
2x(x + 2).
Check this by multiplying back in
2x*x + 2x*2 = 2x^2 + 4x
which is what we started with, so we know we are correct.
