A cuboid with a volume of 374cmcubed
2cm,(x+3)cm and (x+9)
show clearly that that xsquared+12x-160=0
solve the equation by factorisation ,making sure you show the factorisation
show both values of x on the same line
finally,find the dimensions of cuboid ,writing all three on the line
i have gotten this far but i don't know what to do
2(x+3)(x+9)=374
(x+3)(x+9)=187
x=-3 x=-9
x²+27+12x=187
(x+20)(x-8)
x=-20 x=8
x=2,
