Since the center is considered the corner that they both share, here are the answers figure a goes with the first, figure b goes with the last, figure c goes with the second, and figure d goes with the third. Hope this helps.
Answer:
2/3 * 25/1 = 50 / 3 = 16 66/100 = 16 4/25
Step-by-step explanation:
Answer:
17
Step-by-step explanation:
- 38 - 21 = 17
- 21 - 4 = 17
- The difference between each pair of numbers above is 17, so that is the common difference.
I hope this helps!
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:
![a=8,-11](https://tex.z-dn.net/?f=a%3D8%2C-11)
Step-by-step explanation:
![a^2=-3a+88](https://tex.z-dn.net/?f=a%5E2%3D-3a%2B88)
![a^2+3a=88](https://tex.z-dn.net/?f=a%5E2%2B3a%3D88)
![a^2+3a-88=0](https://tex.z-dn.net/?f=a%5E2%2B3a-88%3D0)
![x=\frac{-b\pm\sqrt{b^2-4ac} }{2a}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-b%5Cpm%5Csqrt%7Bb%5E2-4ac%7D%20%7D%7B2a%7D)
![x=\frac{-3\pm\sqrt{3^2-4(1)(-88)} }{2(1)}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%5Cpm%5Csqrt%7B3%5E2-4%281%29%28-88%29%7D%20%7D%7B2%281%29%7D)
![x=\frac{-3\pm\sqrt{9+352} }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%5Cpm%5Csqrt%7B9%2B352%7D%20%7D%7B2%7D)
![x=\frac{-3\pm\sqrt{361} }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%5Cpm%5Csqrt%7B361%7D%20%7D%7B2%7D)
![x=\frac{-3\pm19 }{2}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B-3%5Cpm19%20%7D%7B2%7D)
and ![x=8](https://tex.z-dn.net/?f=x%3D8)
Therefore, the values of
are 8 and -11.
