Answer:
0
Step-by-step explanation:
<span>8 + 3{x - 2[x + 5(x + 3)]}.
=</span><span>8 + 3{x - 2[x + 5x + 15]}
=</span>8 + 3{x - 2[6x + 15]}
=8 + 3{x - 12x -30}
=8 + 3{- 11x -30}
= 8 - 33x - 90
= - 33x - 82
Answer:
17
Step-by-step explanation:
1) if to solve the first inequation, tnen 3x<52; ⇔ x<52/3;
2) if to solve the seconde inequation, then 2x≥24; ⇔ x≥12.
3) according to the items 1 and 2 x∈[12;52/3);
4) the largest prime number is 17.
