The answer is 6(x^2 -1) I have provided a picture with my work and the answer
Answer:
each ouce is worth 25 cents
solution
in order to solve this you need to create proportions so
<u>10 ounces </u>
per $2.50
well you want this to be a unit rate so you would have
<u>10 ounces </u> =<u> 1 ounce</u>
2.50 x
to get to the unit rate, you can see that you divided 10 from 10 ounces so you would do the same to the bottom ...
2.50/10 which is equal to 0.25.
Find the missing angles using either the triangle sum theorem (a2+b2=c2) or inverse trigonometric ratios
A 225 degree angle is equal to 3.92699 radians, but you can round that off to 3.93
