Express 9x3 + 6x2 – 3x in factored form. 3x(x – 1)(3x – 1) 3x(x – 1)(3x + 1) 3x(x + 1)(3x + 1) 3x(x + 1)(3x – 1)

Start by factoring out the GCF, which is 3x:

3x(3x^2 + 2x - 1).  Then factor the trinomial 3x^2 + 2x -1:

3x(3x-1)(x+1)

The length and width of a rectangle have a sum of 90. What dimensions give the maximum area?
tekilochka [14]
w-width\\l-length\\\\2w+2l=90\\2l=90-2w\ \ \ \ /:2\\l=45-w\\\\A=wl\to A=w(45-w)=45w-w^2

Area\ of\ a\ rectangle\ is\ a\ square\ function.\\The\ maximum\ area\ is\ equal\ to\ the\ y-coordinate\ of\ vertex\\and\ "w"\ is\ equal\ to\ the\ x-coordinate\ of\ vertex.\\\\A(w)=45w-w^2\\\\a=-1;\ b=45;\ c=0\\\\x-coordinate\ of\ vertex:\frac{-b}{2a}\\\\w=\frac{-45}{2\cdot(-1)}=\frac{-45}{-2}=22.5\\\\l=45-22.5=22.5\\\\Solution:22.5\times22.5\ \ (This\ rectangle\ is\ a\ square).

vagabundo [1.1K]
First, minus salary
paycheck=comission+salary
paychec-salary=comision

comission/sales=5500/45000=0.122222222/1
pecent means parts ou fo 100
x%=x/100
