Answer:
Step-by-step explanation:
The linear equation in standard form is written in the form :
ax + by = c
Therefore : 12x = -9y + 7 in standard form will be :
12x + 9y = 7
<span>The completely factored form of 9x^2+24x+16 is equal to
</span><span>9x^2+24x+16
(3x + 4) (3x + 4)
Since the two factors are the same, this can be simplified as
</span>(3x + 4) (3x +<span> 4)
</span>(3x + 4)^2
It is a perfect square factor.
I believe the first and last one are polynomials. Usually they start with the highest exponent first and then work their way down.
