Angle 1 and 2 is complementary agles
Answer:
m=-20
Step-by-step explanation:
Let x be the width
Lenght = 10x + 8.1
(10x + 8.1)2 + 2x = 515.6
22x = 499.4
x = 22.7
Area = l*w
= 22.7*235.1
= 5336.77
= 5340( nearest tens)
The <u>root</u> of the <u>function</u> is such point
for which 
The attached graph of the function
shows, that the graph of the function intersects the x-axis in three points (2,0), (3,0) and (4.5,0).
This means that for
- x=2, f(2)=0;
- x=3, f(3)=0;
- x=4.5, f(4.5).
Thus, x=2, x=3 and x=4.5 are rational roots of the polynomial function f(x).
Answer: three rational roots.
