Step-by-step explanation:
Hello there!
Again, just double the given sides.
20+38=58 cm
:)
No solution means u can graph the two equations and it would form parallel lines and would never intersect while, no real solution when graph the two equations would form the same line. When dealing with absolute value equation an equation with a degree larger than one,theres a chance it can be multiple solutions
Answer:
Step-by-step explanation:
let side of cube=x cm
volume=x³ cm³
again side=(x-3) cm
volume=(x-3)³ cm³
x³-(x-3)³=1385
(a³-b³)=(a-b)(a²+ab+b²)
(x-x+3){x²+x(x-3)+(x-3)²}=1385
3(x^2+x²-3x+x²-6x+9)=1385
3(3x²-9x+9)=1385
9x²-27x+27=1385
9x²-27x+27-1385=0
9x²-27x-1358=0
