Answer:
You would have to find the surface area
Step-by-step explanation:
If you had to find something to FILL the room then you would need volume, however, you are working with walls which can be viewed as 2 dimensional, whilst volume is 3 dimensional.
So what you would do is find the surface area of the walls and the ceiling, and then exclude the floor.
If you are given the total surface area, then you need to find the surface area of the floor and subtract it by the total surface area and that will give you how much paint is needed.
Answer:
First one Equivalent but not simplified fully (Can combine the two y terms)
Second: Equivalent but not simplified fully (Can combine the two x^2 terms)
Third: Equivalent and simplified fully
Fourth: Not equivalent (y term is not correct)
Fifth: Not equivalent (x^2 term is not correct and the constant terms [ones without variables] can be combined)
Sixth: Not Equivalent (y term is not correct and the constant terms can be combined)
Step-by-step explanation:
You just need to know if two terms have the same variable they can be added or subtracted. But if it is say x and x^2 it cannot, they need to be brought to the same power as well. or if there is a term with xy, it can only be added and subtracted to other xy terms
Step-by-step explanation:
This polynomial has like terms that can further be simplified
2 - 11x^2 + 6x^2- 8x
2 - 5x^2 - 8x
multiply by negative to take 2 to the right.
-(2 - 5x^2 - 8x)
= 5x^2 + 8x - 2
It's named a Second Degree Polynomial because the highest degree(exponent) of x in the final solution is 2.
it has 3 terms : 5x^2 , 8x , 2
Answer:
$66.25
Step-by-step explanation:
Step one:
given data
Base pay of $55 each day
Paid a $3.75 commission for every computer sale he
let the number of computer be x
and the total be y
y=55+3.75x
Step two:
We are told that maximum is $355
y= 55+3.75x
for x= 3
y=55+3.75*3
y=55+11.25
y=$66.25
3x+5y=42
9x+7y=78
adding above equation
12x+12y=120
x+y=10
