Answer:
12x^3+15x^2-12x+12
Step-by-step explanation:
P(x) = 12x^3 + 11x^2 - 9x + 10
Q(x) = 4x^2 – 3x + 2
P(x) + Q(x) = 12x^3 + 11x^2 - 9x + 10+ 4x^2 – 3x + 2
Combine like terms
=12x^3+11x^2+4x^2-9x-3x+10+2
=12x^3+15x^2-12x+12
Geometry Rule: SOH CAH TOA.
Sine = opposite over hypotenuse
Cosine = adjacent over hypotenuse
Tangent = opposite over hypotenuse
I won't solve all of these for you because I find that solving it on your own is an important step in learning to actually understand how this works.
You will have to use a ruler for this on the chart
D. Inequality
An expression would just contain simple arithmetic without any symbols relating two things to another.
An equation must contain an equals sign.
A fraction will have a bar representing division.
An inequality contains a sign representing a comparison of magnitude, in this question less than <.
Hope this helps!!
