Answer:
9x² - 49
Step-by-step explanation:
A difference of squares factors in general as
a² - b² = (a + b)(a - b)
Given (3x + 7) with a = 3x and b = 7
Then the other factor is (3x - 7)
(3x + 7)(3x - 7)
= (3x)² - 7²
= 9x² - 49

Answer:
Step-by-step explanation:
1. Y varies jointly as R and T
Y = k*R*T
Y = kRT
Where,
k = constant of proportionality
2. B is directly proportional to the square of A and inversely proportional to the cube of C.
B = k(A²) / C³
B = kA²/C³
Where,
k = constant of proportionality
