Answer:
you have four walls. two of them 12*8 and the other two are 10*8 ( we used 8 in both because it's the height of the room). so it goes( 2*12*8)+(2*10*8) and it goes 352S
Step-by-step explanation:
let's say that walls A 12*8 and walls B 10*8. you have 4 walls ta wallpaper.
for walls A= 2*12*8=192
for walls B=2*10*12=160
in total, you need 160+192= 352 square feet of wallpaper
I'm going to use n instead of t
rⁿ=6.25rⁿ+2
minus rⁿ both sides
0=5.25rⁿ+2
minus 2 both sides
-2=5.25rⁿ
divide both sides by 5.25
-2/5.25=rⁿ
take the nth root of both sides
![\sqrt[n]{\frac{-2}{5.25}}= \sqrt[n]{r^n}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7B%5Cfrac%7B-2%7D%7B5.25%7D%7D%3D%20%5Csqrt%5Bn%5D%7Br%5En%7D)
Answer:
A. $1 less
Step-by-step explanation:
24 divided by 8 (unit rate) = $3
28 divided by 7 = $4
4-3=1
For the brownie one it’s C
For the train one it’s B
For the flour one it’s C
You can find the remainder right away by simply plugging in

. The polynomial remainder theorem guarantees that the value of

is the remainder upon dividing

by

, but I digress...
Synthetic division yields
3 | 2 -11 18 -15
. | 6 -15 9
- - - - - - - - - - - - - - - - -
. | 2 -5 3 -6
which translates to

(and note that

, as expected)
