You’re learning the definition of the derivative aren’t you. Just plug in x+h and do FOIL. Then multiply each term by -3 because of -3 infront of the square.
-3(x+h)^2 - 2(x+h) +4
-3[x^2 + 2xh + h^2] - 2x - 2h + 4
-3x^2 - 6xh - 3h^2 - 2x - 2h + 4
Your answer is D
Yes, because every time you subtract 7
Answer:
160ft^2
Step-by-step explanation:
Base area is 80ft^2, and the height of the sandbox is 2 ft.
If you want to fill up the sandbox with sand, you will need 80ft^2 * 2(ft).
Answer:
<em>Correct Answer: D</em>
Step-by-step explanation:
<em>Geometric Sequence
</em>
We can find each term of a geometric sequence if we have the general formula by replacing n for any integer number in the given domain. n must be an integer because it's the position where the term is located. For example, is the term located in position 2, so n cannot be irrational or decimal. The sequence provided is
The variable n starts from 0 and has no limit, so the domain is a set of integers
The angles 90, 40, and 50 are possible for a triangle.
The angles 82, 38, and 60 are possible for a triangle.
And the angles 59, 31, and 90 are possible for a triangle.
This is because the sum of all three angles of a triangle must be 180 degrees.
