Answer:
x > 7/4
Step-by-step explanation:
3(x + 7) < 7(x + 2)
Expand brackets: 3x + 21 < 7x + 14
Subtract 14 from both sides: 3x +7 < 7x
Subtract 3x from both sides: 7 < 4x
Divide both sides by 4: 7/4 < x
Therefore x > 7/4
Answer:
Step-by-step explanation:
9*21*2+18*9*2+21*18+35*20+(35*20-21*18)+35*15*2+15*20*2
= 378 + 324+ 378 + 700 + 700 - 378 + 1050 + 600
= 3752
