Answer:
-22
Step-by-step explanation:
The function y=400-22x is a linear equation in the form y=mx + b. Although they put "mx" after "b" so the equation doesn't start with a negative.
"m" is rate of change, or the slope if graphed.
The negative means "y" decreases as "x" increases. On a graph, it decreases left to right.
Length= 5x-2 because 15x^2-10x-9x+6 is (5x-2) and (3x-2)
LW=A
L={(5x-2)(3x-2)}/(3x-2)=5x-2
A 40 degree angle: go from the right positive side of the x-axis and go left (left is positive degrees) forty degrees, which is a little less than halfway in quadrant 1.
Answer: 
Step-by-step explanation:
We know that the circumference of a circle is given by :-
, where r is the radius of the circle .
Given : Circumference of circle = 16 cm
Then, 
i.e 
(1)
We know that the area of circle is given by :-
i.e. 
[From (1)]
i.e. 
i.e. 
Put 
Hence, area of circle =
multipl 10×2=20 y ese es el resultado entendes ?
