Answer:
The bag of eight hot dog buns is a better deal.
Step-by-step explanation:
2.60 divided by the eight hot dog buns comes out to about 0.33 cents per bun, while the bag that is 4.60 divided by the twelve hot dog buns would come out to about 0.35 cents per bun. Hope this helps.
That’s really rude man, be nice to people
Answer:
Nvm there right
Step-by-step explanation:
Extranious solution is mostly when you take the square root of negative number
what you want to do is math stuff
translate
remember that
![x^ \frac{1}{2} = \sqrt{x}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7B1%7D%7B2%7D%20%3D%20%5Csqrt%7Bx%7D%20)
so
![x^ \frac{3}{2}=x \sqrt{x}](https://tex.z-dn.net/?f=x%5E%20%5Cfrac%7B3%7D%7B2%7D%3Dx%20%5Csqrt%7Bx%7D%20%20)
7.
![(x+1) \sqrt{x+1} -2=25](https://tex.z-dn.net/?f=%28x%2B1%29%20%5Csqrt%7Bx%2B1%7D%20-2%3D25)
add 2 to both sides
![(x+1) \sqrt{x+1}=27](https://tex.z-dn.net/?f=%28x%2B1%29%20%5Csqrt%7Bx%2B1%7D%3D27)
square both sides
![(x+1)^3=729](https://tex.z-dn.net/?f=%28x%2B1%29%5E3%3D729)
cube root both sides
x+1=9
minus 1
x=8
8.
square both sides
![3x+7=x^2-2x+1](https://tex.z-dn.net/?f=3x%2B7%3Dx%5E2-2x%2B1)
using math
0=x²-5x-6
x=6 or -1
if we do x=-1, we get
√4=-2, which is kind of true, but we normally find the principal root (posiitive0
-1 is extraious
x=6
9.
add √(x-1) to both sides then square both sides
![2x+6=4 \sqrt{x+1}+x+5](https://tex.z-dn.net/?f=2x%2B6%3D4%20%5Csqrt%7Bx%2B1%7D%2Bx%2B5)
minus (x+5) from both sides
![x+1=4 \sqrt{x+1}](https://tex.z-dn.net/?f=x%2B1%3D4%20%5Csqrt%7Bx%2B1%7D%20)
square both sides
![x^2+2x+1=16x+16](https://tex.z-dn.net/?f=x%5E2%2B2x%2B1%3D16x%2B16)
using math
x=-1 or 15
if we had x=-1, we would be having √(-1-1) which is sqrt of negative which is not allowed
x=15
Answer:
24 degrees
Step-by-step explanation:
The sum of the exterior angles of a triangle is 360 degrees
2x + 6x + 7x = 360
15x = 360
x = 24
