Question

3x square - 2y sqaure

Answer 1

Answer:

3x² - 2y²

BY, a² - b² = (a+b) (a-b)

-----> (3x + 2y) (3x-2y)

Step-by-step explanation:

According to the Question

Let the ratio be 5x : 4x

Total number of people in group = 72

We need to calculate the number of lawyers in the group & it is also given that the ratio of doctor to lawyers is 5:4

Sun of Ratios = Total number of people

Substitute the value we get

:\implies:⟹ 5x + 4x = 72

:\implies:⟹ 9x = 72

:\implies:⟹ x = 72/9

:\implies:⟹ x = 8

Now, putting the value of x = 8

4x = 4×8 = 32

Answer 2

Answer:

(3x+2y)(3x-2y)

these is the answer
