√200 = √2·100 = √2 · √100 = 10√2
This is a form of the Pythagorean Theorem. We just need to know how far we went in the x direction and how far in the y direction then use
a^2 + b^2 = c^2 to find the value.
distance in the x direction (-4 to -4) that's easy it didn't move. so that is zero and thus would make the distance all in the y direction.
To move from 8 to -8 we take (8 - (-8)) = 8 + 8 = 16 which is your answer
Answer:
7%
Step-by-step explanation:
5 years= $1,400
1 year= 1,400/5= 280
$280 is ?% of $4,000
(280/4000)*100
so, 7%
Hope this helps!
Answer: 48 cm^2
Step-by-step explanation:
The equation for the area of a triangle is 1/2(base*height). Plug in the numbers to get an equation of 1/2(8*12). 8*12 = 96. Now divide by 2. 96/2 = 48.
You have to get rid of 1/2 by multiplying it by its recriprocal which is like this:
1) 1/2 x 2/1 which equals to zero and you do the same to the other side.
2) -12 x 2/1 = -24x then multiply-24x with 7 which equals -168.
16-x= -24x -168
3) subtract 16 to the other side and subtract 24x with x
23x= -184
4) divide by 23 to isolate x and you get -8
5) x=-8
