Width = 13cm
Length = 16cm
<u>Explanation:</u>
Let width = b,
So, length = b+3
Perimeter of rectangle = 2x(length + width)
According to the question,
Hence,
Width = 13cm
Length = 16cm
It's 25 percent.............

Answer:
(1) Required function is . (2) Slope of line is .
Step-by-step explanation:
1)
The function passing through (-3,9), (-1,3), (0,0) and (3,-9).
From these points it is noticed that the value of function decrease by 6 if the value of x increases by 2 and y-intercept is (0,0).
Slope intercept of a line is
Where, m is slope and b is y-intercept.
So, function is defined as
The required function is .
2)
It is given that the line joining two points (10, 9) and (40, 3).
Slope of line is
Therefore slope of line is .
Answer:
f(x) = (x + 10)(x + 4)(x - 1)
Step-by-step explanation:
Given the zeros of a polynomial, say x = a and x = b, then
the factors are (x - a) and (x - b)
The polynomial is then the product of the factors
f(x) = (x - a)(x - b)
Here the zeros are x = - 10, x = - 4 and x = 1, thus the factors are
(x - (- 10)), (x - (- 4)) and (x - 1), that is
(x + 10), (x + 4) and (x - 1)
f(x) = (x + 10)(x + 4)(x - 1)
