What your going to want to do is take graph paper each square is five feet draw whatever shape your room is on it and take perimeter and area I cant write the reflection as I don't know what room you have drawn.
First one is 7.73 (23.19/3)
Second one is 14.04 ((19.71/7.3) x 5.2)
Answer:
A) 5
Step-by-step explanation:
The coefficients of the second equation are 1/3 of those of the first equation. If the constant of the second equation is also 1/3 of the constant of the first equation, then the equations are <em>dependent</em>, and will have an infinite number of solutions.
The constant must be something other than 1/3·15 = 5 to make the equations <em>inconsistent</em>, having no solutions.
The answer would be the distances that are not too large and not too small
A.legnth and width of a ball room
this would work because the next measurement is 1 mils and ball rooms are not that big
B. width of an eyelash. that is rediculously small so this is wrong
C. distanc from chicaco to san fransisco
way too far, use miles
D. height of a door
corect, door is apout 8 feet aprox
answer is A and D
Answer:
8x²- x -8
Step-by-step explanation:
The question is not well written. I guess what you mean is:
Subtract -2x^2+4x-1 ( minus 2x squared plus 4x minus 1) from 6x^2+3x-9 (6x squared plus 3x minus 9).
To subtract -2x^2+4x-1 from 6x^2+3x-9, that is
6x^2+3x-9 - (-2x^2+4x-1). This can be written as
6x²+3x-9 - (-2x²+4x-1)
Now, opening the bracket, we will get
6x²+3x-9 +2x²-4x+1
Then, collecting like terms, we get
6x²+2x²+3x-4x-9+1
6x²+2x² = 8x²
3x-4x = -x
-9+1 = -8
∴6x²+2x²+3x-4x-9+1 becomes
8x²-x -8
The answer is 8x²-x -8.
