The system is "inconsistent".
The first and last equations describe parallel lines:
x +2y +3z = 12
x +2y +3z = 60
There are no values of x, y, and z that can satisfy both equations.
Factoring:
your equation: x^-4xy+3y^
now figure out what adds to -4 and multiplied to +3 (-3&-1)
use that information to factor.
you get: (x-3y)(x-y)
now use the distributive property to make sure it's the right answer: x^-xy-3xy+3y^
this means (x-3y)(x-y) is correct.
hope this helped :)

Answer:
<h2>1544 m³</h2>
Step-by-step explanation:
surface area = 2 × base + lateral area
base = (10×20)÷2 = 100
Lateral area = perimeter × height
= (20+14+14)×28
=1 344
Final answer :
surface area = 2 × base + lateral area
= 2 × 100 + 1344
= 200 + 1344
= 1544
