Answer:
7x^2a
Step-by-step explanation:
7x^3a+7x^2a^2
7x^3a = 7 xxxa
7x^2a^2= 7 xxaa
The common terms are 7xxa
7x^2a
This is the greatest common factor
LCD would be 18
8/9 = 16/18
2/3 = 12/18
1/9 = 2/18
240 is 240% of 576
240% x 240 = x
(240 x 240) divide by 100
57,600 divide by 100 = 576
x = 576
Answer:
-1/7 y + 1/7 x
Step-by-step explanation:
Can also be written as
1/7 x - 1/7 y
Answer: True.
The ancient Greeks could bisect an angle using only a compass and straightedge.
Step-by-step explanation:
The ancient Greek mathematician <em>Euclid</em> who is known as inventor of geometry.
The Greeks could not do arithmetic. They had only whole numbers. They do not have zero and negative numbers.
Thus, Euclid and the another Greeks had the problem of finding the position of an angle bisector.
This lead to the constructions using compass and straightedge. Therefore, the straightedge has no markings. It is definitely not a graduated-rule.
As a substitute for using arithmetic, Euclid and the Greeks learnt to solve the problems graphically by drawing shapes .
