Every single one of those expressions factor. When factored, this is what we have:

. After canceling out like factors, what we are left with is this:

. That means that b = 9, c = 1, and d = -2
Answer:
1a the square root of 37
1b the same as a
2 y=3x+2
Step-by-step explanation:
a and b use the distance formula
for number 2 use rise over run to find the slope and find where the line intersects to find the y intercept.

How long does it take her to do a lawn? If it took her 5 hours for 1 lawn then it would be $840 for twelve lawns.
She is getting paid $14 an hour.
Answer:
Left angle = 60°
Top angle = 120°
Right angle = 60°
Step-by-step explanation:
Use what you know about angle relationships to set up equations you can solve for each variable.
The top top angle, for example, added to one of the other angles must equal 180° because they are supplementary.
You have two variables, so you need at least two equations (I made three but only used two).
The work is in my attachment, comment of you have questions.
