Answer:
This question is very big, you should shorten your question a bit so that I can answer it quickly, the rest is just that I did not understand the question a bit
Answer:

Step-by-step explanation:
Given

Required
Express in standard form
To do this, we simply reorder the terms of the polynomial in descending order of power.
So, we have:

10000x8%= $800 anually
anually=yearly
800x18=14400
In the given expression 6X² + 13X +6, we can easily identify the values of a, b and c. These values are a=6, b=13 and c=6
For the value of "ac", we have:
ac=6*6
ac=36
For a sum of b are 4, we have
ac+b=36+13=49
Therefore, the answer for the last question "The two numbers that have a product of ac and a sum of b are 4 and 9".
Answer:
they form a 90 degree angle
Step-by-step explanation:
perpendicular (⊥) always implies 90 degree angles
parallel (║) always implies they never intersect
