Ответ:
(7; 3); (11; 7); (17; 13); (23; 19)
Пошаговое объяснение:
простые числа:
2, 3, 5, 7, 11, 13, 17, 19, 23
7 - 3 = 4
11 - 7 = 4
17 - 13 = 4
23 - 19 = 4
<span>1302 - 2(4x + 1) = 200
1302 - 8х - 2 = 200
1300 - 8х = 200
8х = 1300 - 200
8х = 1100
х = 1100 : 8
х = 137,5</span>
Int {2}_{5} (x+3-x^2+6x-13) dx = int {2}_{5} (-x^2+7x-10) dx = -x^3/3 +7x^2/2 - 10x | {2}_{5} = -5^3/3 +7*5^2/2 - 10*5 - (-2^3/3 +7*2^2/2 - 10*2) = -125/3 + 175/2 - 50 +8/3 - 28/2 + 20 = -117/3 + 147/2 - 30 = (-234+441)/6 - 30 = 207/6 - 30 = 34.5 - 30 = 4.5
