Answer:
the sum of the first 6 terms =189
Step-by-step explanation:
the first 6 terms-
96,48,24,12,6,3
I found them easily by dividing 48 with random small numbers until I got 6 for the fifth term. So here I divided 48 by 2 which is = 24(3rd term), then divided 24 by 2 which is =12(4th term) and then again decide the answer by 2 and finally got 6 for the 5th term. So the ratio is 1/2. For the first term I did the opposite, multiply 48 by 2 which is = 96. And lastly find the sixth term and add them up which is = 189
I tried my best to explain it in simple terms, hope this helps:)
Hi there! The answer is A.
(2x² + 3x - 10) - (x² - x + 111)
Let's solve this problem step by step!
First work out the parenthesis. Because we multiply by negative 1, we mustn't forget to change the symbols in front of the factors.
2x² + 3x - 10 - x² + x - 111
Now rearrange our expression, in order to collect the terms later.
2x² - x² + x + 3x - 10 - 111
And finally collect the terms.
x² + 4x -121
The answer is A.

1. Rational/The sum of two rationals is always rational
2. Irrational/ the sum of a rational and an irrational is always irrational
3. Irrational/The product of a nonzero rational and an irrational is always irrational
4. Rational/The product of two rationals is always rational
Pretty much all the irrational numbers are the ones with radical signs over them and the rational numbers are the fractions and whole numbers. Once you identify the two numbers to be rational or irrational, you can then find your answer within the second part of the answers.
Answer:
Step-by-step explanation:
Since, By the given diagram,
The side of the inner square = Distance between the points (0,b) and (a-b,0)
Thus the area of the inner square = (side)²
Now, the side of the outer square = Distance between the points (0,0) and (a,0),
Thus, the area of the outer square = (side)²
Hence, the ratio of the area of the inner square to the area of the outer square
