Length(l)= 2w
width(w)= w
Perimeter(P)= 2w+2l= 72 (simplify expression: divide each side by 2 )
P= w+l= 36 (plug in "2w" for "l")
P= w+(2w)= 36
P= 3w= 36 (divide each side by 3 to find the width)
w= 12 units
find length:
l=2w
l= 2(12)
l= 24 units
Answer:
The length of this rectangle is 24 units and the width is 12 units.

Answer:
x=22
Step-by-step explanation:
break it down:
55-11 = 44
so 44/2 = 22
therefore
x=22
We have the following:
AC=root(a^2 + b^2)
Then,
BD=root((a-0)^2 + (0-b)^2)
BD=root((a)^2 + (-b)^2)
BD=root((a)^2 + (b)^2)
therefore,
AC=AB
Answer:
AC=AB
The total distance traveled by the particle from t = 0 to t = 3 seconds is given by
![\int\limits^3_0 {(t^2-4)} \, dt =\left[ \frac{t^3}{3} -4t\right]_0^3 \\ \\ = \frac{3^3}{3} -4(3)=9-12=\bold{-3}](https://tex.z-dn.net/?f=%20%5Cint%5Climits%5E3_0%20%7B%28t%5E2-4%29%7D%20%5C%2C%20dt%20%3D%5Cleft%5B%20%5Cfrac%7Bt%5E3%7D%7B3%7D%20-4t%5Cright%5D_0%5E3%20%5C%5C%20%20%5C%5C%20%3D%20%5Cfrac%7B3%5E3%7D%7B3%7D%20-4%283%29%3D9-12%3D%5Cbold%7B-3%7D)
