Question

7. The area of a rectangle is (6x2 – 7x – 5) m². If its length is (2x +1) m, then find the breadth of rectangle​

Answer 1

Answer:

AREA OF RECTANGLE = L× B

(6x²-7x-5). = (2x+1)×B

[6x²-(10x-3x)-5]. = (2x+1 )×B

[6x² - 10x + 3x - 5] = (2x+1) × B

[2x(3x-5) +1(3x-5)] = (2x+1) ×B

(2x+1) (3x - 5). = (2x+1) ×B

( 2x+1) (3x - 5)/(2x+1) = B

(3x- 5) = B
