Answer:
-12u+8w+16
Step-by-step explanation:
to get rid of the parenthesis you multiply everything that is inside of the parenthesis by -4
-4x3u=-12u
-4x-2w=8w
-4x-4=16
then we just add everything together and end with
-12u+8w+16
hope this helps (;
Note that subtracting a negative number from another number is equivalent to adding the magnitude of the negative number to the other number. Thus,
subtracting -1 2/3 from 5 1/2 is equivalent to adding 1 2/3 to 5 1/2.
Here the LCD is 3(2) = 6. Let's add 1 4/6 to 5 3/6. We get 6 7/6, or more properly, 7 1/6 (answer).
Hi Softballgirl6! I would say that first, we could pretend that the zeros don't exist because we could add those in later. Then just working with 1x2x3x4, we could mentally solve this to 24 and then add in the extra 4 zeros that we left out at the beginning. This brings the answer to 240000. Hope this helps! :)
Answer:
c = 24.34
Step-by-step explanation:
Here, we can use the cosine rule
Generally, we have this as:
a^2 = b^2 + c^2 - 2bcCos A
12^2 = 14^2 + c^2 - 2(14)Cos 19
144 = 196 + c^2 - 26.5c
c^2 - 26.5c + 196-144 = 0
c^2 - 26.5c + 52 = 0
We can use the quadratic formula here
and that is;
{-(-26.5) ± √(-26.5)^2 -4(1)(52)}/2
(26.5 + 22.23)/2 or (26.5 - 22.23)/2
24.37 or 2.135
By approximation c = 24.34 will be correct
The point (-11,34) has the coordinates x = -11 and y = 34
The point (47,0) has the coordinates x = 47 and y = 0
Let's focus on just the x coordinates of each point for now. Those values are -11 and 47. Add them up to get -11+47 = 36. Then divide by two to end up with 36/2 = 18
The x coordinate of the midpoint is x = 18
Repeat those steps for the y coordinates. First add them up: 34+0 = 34. Then divide by two: 34/2 = 17
The y coordinate of the midpoint is y = 17
<h3>Therefore the midpoint is located at (x,y) = (18,17)</h3>
--------------------------
side note:
If you want, you can use the formulas
xm = (x1+x2)/2
ym = (y1+y2)/2
where (x1,y1) and (x2,y1) are the two endpoints and (xm, ym) is the midpoint. Though this method may be a bit confusing.
