Option B: (b-a)/(b+a) is the correct answer
Step-by-step explanation:
The given expression is;
First of all we have to take LCM in both numerator and denominator
So,
The reciprocal of the denominator will be multiplied with the numerator for simplification
So,
Hence,
Option B: (b-a)/(b+a) is the correct answer

Step-by-step explanation:
step 1. a circle with r = 2 has area of (pi)r^2 = (pi)(4) = 4pi
step 2. a circle with r = 3 has area of (pi)r^2 = (pi)(9) = 9pi
step 3. the area, A, of a circle is half the sum of the area of the circles with r = 2 and r = 3
step 4. A = (4pi + 9pi)/2 = 13pi/2 = 6.5(pi).
step 5. the answer is not 6.5 but is 6.5(pi) or 6.5 times pi.

Answer:
(2x + 7)(2x - 7)
Step-by-step explanation:
Given:
4x² - 49
Find:
Factories
Computation:
4x² - 49
Using Identity
⇒ a² - b² = (a + b)(a - b)
⇒ 4x² - 49
⇒ (2x)² - (7)²
(2x + 7)(2x - 7)
