PLZ HELP I HAVE NO CLUE WHAT TO DO

142 cm^2

Step-by-step explanation:

2(L*H)+2(L*W)+2(W*H)=SA

7*3=21

21*2=42

7*5=35

35*2=70

5*3=15*2=30

30+70+42=142

an

y = 6x -3y -12

y +3y +12 = 6x

=> . x = { 2y / 3 +2 } this is equation of line in terms of x

=> . if line meets the x-axis the co-ordinates of meeting point would be ( x , 0 )

=> . x = 2 ( 0 ) / 3 + 2

=> . x = 2

so, the point is ( 2 , 0 )
