Answer:
What is the question?
Step-by-step explanation:
X^2 + y^2 - x^2 +y^2
That would be (1x+1y)-(1x+1y)
Part A: First, list multiples for each number. The multiples of 5 are: 5, 10, 15, 20, 25 30, 35, 40, 45, 50, 55, 60, etc. The multiples of 12 are: 12, 24, 36,48, 60, etc. The least common multiple is the first common multiple between the two, in this case being 60. The LCM of 5 and 12 is 60.
Part B: SImilar to above, list all factors for each number. 72: 1, 2, 3, 4, 6, 8, 9, 12, 18, 24, 36, and 72. 81: 1, 3, 9, 27, and 81. The greatest common factor is the highest common number, 9 in this case. The GCF of 72 and 81 is 9.
Part C: To rewrite, we need to take out the 9 by dividing. 72/9 is 8. 81/9 is 9. Therefore, we would get 9(8+9), to equal 153. Your answer here is 9( 8 + 9 ). Hope this helped!
Answer:
C i think
Step-by-step explanation:
divide both sides by b, then multiply both sides by 2 and get 2A/b =h
10a - 5b = 25
10a - 10a - 5b = 25 - 10a
-5b = -10a + 25
-5 -5
b = 2a - 5
