Question

find the value of the product
(4x+3y)(3y-2y+5) when x=1/3 and y=2/5​

Answer 1

Answer:

1014÷75 = 13.52

Step-by-step explanation:

(4x+3y)(3y-2y+5) = (4x+3y)(y+5)

= (4x)(y) + (4x)(5) + (3y)(y) + (3y)(5)

=> 4xy + 20x + 3y² + 15y

putting value of x & y

=> 4(1/3)(2/5) + 20(1/3) + 3(2/5)² + 15(2/5)

= 8/15 + 20/3 + 2(4/25) + 6

= 8/15 + 20/3 + 8/25 + 6

taking LCM , of 1,3,15,25 = 75

=> { (8×5) + (20×25) + (8×3) + (6×75) } ÷ (75)

= ( 40 + 500 + 24 + 450 ) ÷ 75

= 1014÷75 = 13.52
