Using the distributive property, we have -12w^2-2w since a(b+c)=ab+ac
Hope this helped
You have coordinates of tree T(16,21) and of rock R(3,2). Let S be a point that denotes treasure. Since treasure is buried so that it partitions the distance between a rock and a tree in a 5:9 ratio, you can state that

Find the coordinates of these vectors:

Then
and
Solve these two equations:
1.

2.

Answer: the treasure are placed at point (7.6,8.8), so the correct choice is B.
It’s 121 feet bc 484 divided by 4 (because there’s 4 sides to a fenced area) is 121
Answer:
Vertical line will be x=0, and horizontal line will be y=-3
Step-by-step explanation:
Draw a vertical line through point (0,-3). You will see it's on the y-axis. The equation of the line on y-axis is always x=0, because no matter what point you choose on the line, the x coordinate will be 0. (0,-3), (0, -2), etc.
Next draw a horizontal line through (0,-3). It's parallel to the x axis, and no matter what point on the line you choose, the y coordinate will be -3. (0,-3), (1, -3), etc
(-32/7,281/21) is the answer
