It is not.
400 decimeters = 4,000 cm
4,000 cm = 40 m
Answer:
<1 = 100
<2 = 80
Step-by-step explanation:
Angle 1 and angle 2 are supplementary
Supplementary angles add to 180 degrees
<1 + <2 = 180
The angles are in a ratio of 5 to 4
Multiply by x to get the measure of each angle
<1 = 5x <2 = 4x
5x+4x = 180
Combine like terms
9x = 180
Divide by 9
9x/9 =180/9
x =20
<1 = 5x = 5*20 = 100
<2 = 4x = 4*20 = 80
Since this polynomial has 4 terms, factoring by grouping should be the first thing we try here.
So, we have:

So, we can use ZPP to find out roots:

So our three roots are:
