Answer:
Step-by-step explanation:
Length = x+3
Width = x-1
Area = l*b
where l is the length of the bedroom
and b is the breadth or width of the bedroom
The polynomial can be written as:
Area=(x+3)(x-1)
Now we will find the area of the room when x=10
First we will find the values of length and width.
Length = x+3
Length = 10+3 = 13
Width = x-1
Width = 10-1=9
Now put the values in the formula:
Area=l*b
Area=13*9
Area = 117 square feet....
Answer:
About 11.4
Step-by-step explanation:
There are 3.78541178 liters in a gallon.
Round that up to the nearest 100 and you get 3.8
Multiply 3.8 by 3.
You get 11.4
(4x+3y=-13) * 2
(-5x+2y=-24)*3
_____________
8x+6y=-26
-
-15x+6y=-72
___________
23x=46
X=2
Replace all the x values with -3
f(-3)=-2(-3)^2+5(-3)
f(-3)=2(9)-15
f(-3)=18-15
f(-3)=3
Hope I helped :)
