Answer:
3r^3-27r, the main thing that is gonna help you to solve for this is by using FOIL.
Answer:
D
Step-by-step explanation:
You are looking for sin, which is the opposite side over the hypotenuse. You can use "<u>S</u>ome <u>o</u>ther<u> h</u>ippy<u> c</u>aught <u>a</u>nother <u>h</u>ippy <u>t</u>ripping <u>o</u>n <u>a</u>cid" to remember <u>S</u>in=<u>o</u>pposite/<u>h</u>ypotenuse; <u>C</u>os= <u>a</u>djacent/<u> h</u>ypotenuse; <u>T</u>an= <u>o</u>pposite/<u>a</u>djacent.
Answer:
Step-by-step explanation
subtract 8 from both sides
8-2x-8=-4x+4-8
simplify
-2x=-4x-4
add 4x to both sides
-2x+4x=-4x-4+4x
Simplify
2x=-4
divide both sides by 2
2x/2=4/2
simplify
x=-2
Answer:
right
neither
straight
neither
Step-by-step explanation:
The first angle is a right angle. The box in the corner indicates a 90 degree angle
The second angle is less than 90 degrees so it is an acute angle
The third angle is a straight line so it is a straight angle.
The fourth angle is wider than 90 degrees it is an obtuse angle
Perform the operation given that a = {−3, −2, −1, 0, 1, 2, 3}, b = {−4, −2, 0, 2, 4}, and c = {0, 1, 2, 3, 4}. (enter your answe

A ∩ c={0,1,2,3}
b ∪ (a ∩ c)={-4,-2,0,1,2,3,4}
