Note: a² - b² = (a-b)(a+b)
9x² - 16y² = (3x)² - (4y)² = (3x - 4y)(3x + 4y)
SOLUTION:
Step 1:
In this question, we are given the following:
Step 2:
The details of the solution are as follows:
Step 3:
Now, from the solution above, we can see that the value of the integrand CONVERGES to a number that is approximately 0.41634
Let number be x and x+13
Then x+x+13=15 (A/q)
2x+13=15
2x=2
X=1
:. X+13= 14
Two numbers are 1 And 14
To easily solve for the ratios, divide the weight by the mass.
196/20 = 9.8
9.8 is your multiplier.
Divide 1078 by 9.8
1078/980 = 110
X = 110
Your question is the ratio of weight to mass, so from right to left.
Your correct answer is B.)
