hope this helps you
Multiply 3x*4=12x -6*4=-24 so 12x-24=24 add 24 and it would be 12x=48 divide by 12 and x=4
Solving for (x,y)
(x-y=8)
(x=y-8) & (y=x-8)
solving for (y,x)
(2y=2x-16)
(y=x-8)&(x=y+8)
Answer:
190 cm^2
Step-by-step explanation:
There are 2 congruent square bases: 5 cm * 5 cm * 2 = 50 cm^2
There are 4 congruent rectangular sides: 5 cm * 7 cm * 4 = 140 cm^2
Total surface area: 50 cm^2 + 140 cm^2 = 190 cm^2
