Answer:
Step-by-step explanation:
Means a question in which we have to use mathematical calculations to solve and get solutions
<span>The perimeter of a rectangle is:
P = 2(l + w)
So we have:
P = 2(l + x)
This is one of our expressions.
It says the length is 3 times the width.
So we have 3 * x or 3x.
We can write:
l = 3x
Now plug this into the formula:
P = 2(l + x)
Plug in '3x' for 'l'</span>
Answer:
2.75 is the closest hope this helps ^-^
AB is divided into 8 equal parts and point C is 1 part FROM A TO B, so the ratio is 1:7, with C being 1/7 of the way. The ratio is k, found by writing the numerator of the ratio (1) over the sum of the numerator and denominator (1+7). So our k value is 1/8. Now we need to find the rise and the run (slope) of the points A and B.
![m= \frac{5-9}{9-(-3)}](https://tex.z-dn.net/?f=m%3D%20%5Cfrac%7B5-9%7D%7B9-%28-3%29%7D%20)
. That gives us a rise of -4 and a run of 12. The coordinates of C are found in this formula:
![C(x,y)=[ x_{1} +k(run), y_{1} +k(rise)]](https://tex.z-dn.net/?f=C%28x%2Cy%29%3D%5B%20x_%7B1%7D%20%2Bk%28run%29%2C%20y_%7B1%7D%20%2Bk%28rise%29%5D)
. Filling in accordingly, we have
![C(x,y)=[-3+ \frac{1}{8}(12),9+ \frac{1}{8}(-4)]](https://tex.z-dn.net/?f=C%28x%2Cy%29%3D%5B-3%2B%20%5Cfrac%7B1%7D%7B8%7D%2812%29%2C9%2B%20%5Cfrac%7B1%7D%7B8%7D%28-4%29%5D%20%20)
which simplifies a bit to
![C(x,y)=(-3+ \frac{3}{2},9- \frac{1}{2})](https://tex.z-dn.net/?f=C%28x%2Cy%29%3D%28-3%2B%20%5Cfrac%7B3%7D%7B2%7D%2C9-%20%5Cfrac%7B1%7D%7B2%7D%29%20%20)
. Finding common denominators and doing the math gives us that the coordinates of point C are
![(- \frac{3}{2}, \frac{17}{2})](https://tex.z-dn.net/?f=%28-%20%5Cfrac%7B3%7D%7B2%7D%2C%20%5Cfrac%7B17%7D%7B2%7D%29%20%20)
. There you go!
