Answer:
(-∞,-4)
Step-by-step explanation:
1. Move like terms together
-4x + 18 ≤ - 2 -9x
Move -9x, the sign changes to a positive
-4x + 18 +9x ≤ -2
Move 18, the sign changes to a negative
-4x + 9x ≤ - 2 -18
2. Combine like terms
-4x+9x becomes 5x
-2-18 becomes -20
The new equation is 5x≤-20
3. Divide both sides by 5
5x÷5=x
-20÷5=-4
x≤-4
4. Write in interval notation
Answer:
D. Natural Numbers, wholes, and integers.
Your answer is the third option.

Answer:
(d/2)^2 pi
Step-by-step explanation:
To find the area of a circle the formula is A=pi times radius sqaured. Since we do not have the radius we need to find it. The radius will always be half the diameter hence the (d/2). This will give us the radius, next is just to complete the area formula by squaring the radius and multiplying it by pi. i hope this helps :)
