This may look scary, but all you have to do is distribute, first:

Now it's much easier (remember to distribute the negative):

So, the entire thing simplifies to
-2c. NEAT!
Answer:
7.5 = OM
Step-by-step explanation:
Since this is a right triangle, we can use trig functions
sin theta = opposite side / hypotenuse
sin 30 = OM / UN
sin 30 = OM / 15
15 sin 30 = OM
7.5 = OM
Answer:
-3ad/2 -2bd = c
Step-by-step explanation:
3a + 4b = 1 - 2c/d
⇒3ad + 4bd = d - 2c [multiply d on both sides]
⇒3ad + 4bd - d = -2c [subtract d on both sides]
⇒3ad/(-2) + 4bd/(-2) = c [divide -2 on both sides]
⇒-3ad/2 -2bd = c
Answer:
-2, -1
Step-by-step explanation:
the x same cause if you reflect across the x-axis so you move on the y-axis. and reflect means the same distance from the point you reflect (that it was 1 cause it was 1 point above the x-axis) just negative so -1 now. if the original point was -2,-1 so the answer was -2,1.
18 1/2 :)
Explanation: Leave the 18 as it is then split 5 in half =2.5
