Answer:
x=-5, x=-9
Step-by-step explanation:
Use zero product property to set each term to 0: x+5=0, x+9=0.
x=-5, x=-9
350 + 4x = 750
x = the amount the fee went up annually.
4x = 750 - 350
4x = 400
x = 400/4
x = 100
The rate of change is 100 dollars per year. The initial value of her business is 350 dollars. To check your work (aka how do you know) if you add 100 dollars to her initial value (350) 4 times you get 750.
This can be
solve using sine law, first solve the angle created at the steeple, x
X = 180 – 40 –
32
X = 108 degrees
Solve one side,
opposite to 32 degree angle, side a
Sine law:
Sin ( 32 ) / a =
sin ( 108) / 50
Solve for a
a = 27.86 m
then
sin (40) = h /
27.86
solve for h
<span>h = 17.91 m high
is the steeple</span>
Answer: B.
Step-by-step explanation: you divide how many people there are overall by the amount selected, If the number is above one, at least one gets a soda. If it is below, none get a soda. If it is all of them, them they all get a soda.

Step-by-step explanation:
Ana started the work nicely by multiplying out factors to get:\
She multiplied correctly using difference of two squares to get:
Unfortunately: She made a mistake in multiplying she mistakenly got instead of . <em>She left out the coefficient of 2.</em>
Therefore the second step should have been:
The next step will now be:
This simplifies to
