well
length will be:
(27+3x)m
width will be
(25+ x)m
so what question says is
area of large lawn = 2x area of small lawn
(27+3x)(25+x) = 2(27 x 25)
675 + 27x + 75x + 3x^2 = 1350
3x^2 + 102x - 675 = 0
now divide both sides by 3
(3x^2 + 102x + 675)/3 = 0/3
x^2 + 34x + 225 = 0

hope it helps

I got it till 3x^2+102x - 675 but y dividing by three ?
Btw thnx !

Divide both sides by 3 so you'll get the equation as shown in the question paper. Besides, the simplest form is always the best

Btw thnx !

because its 3 times the earlier area..which means it was y and now its 3y..so youll divide it b 3!!

Thnx alot

I made the equation after the equal part the same but y the 3y ?

like i said because it is 3 times than the previous y!!

Btw thnx !

yea...u have to bring the answer.. the question hints u by saying reduce it to so it got reduced by division

? -.- ?

the one who wanted to know got it!!
and you know already so....

Terrible question: -.-

B = 3k

Express 9^(2k+2) in terms of B

Terrible question: -.-

B = 3k

Express 9^(2k+2) in terms of B

shouldnt it be 3^k?
