ANSWER
2x-3=0
and
x+4=0
EXPLANATION
Given that:

Then to find roots of

is the same as finding the roots of

By the zero product property, we must have either,

Hence the equations that must be solved to find the roots are:
2x-3=0
and
x+4=0
A composite number is a number with more than 2 factors and 16, 18, 20, and 21 are composite.
Answer: 2.225 kg
Step-by-step explanation:
You know that:
- The total weight the farmer sold was 8.9 kilograms.
- 3/4 of this weight is apples, and the rest is pears.
Therefore, to calculate the amount of kilograms of pears she sold at the farmer's market (which you can call x), you need to apply the following proccedure.
Thefore, you obtain the following result:

Answer/Step-by-step explanation:
A linear pair is formed when two straight lines intersect to form two angles that are adjacent to each other and are on a straight line. The sum of both adjacent angles equals 180°.
From the diagram given, examples of linear pair are:
<FEG and <GEN
<CDE and <ADC
These are some of the few examples we can see in the given diagram that are linear pairs.
