Answer 1

Объяснение:

1.

$x = (2 \times 3 + 3 \times 2 + 4 \times 4 + 5 \times 4) \div 13 = (6 + 6 + 16 + 20)= 48 \div 13 = 3.692$

2.

1)

$(4 \times 3 + 9 \times 2 + 16 \times 4 + 25 \times 4) \div 13 = (12 + 18 + 64 + 100) \div 13 = 194 \div 13 = 14.923$

2)

$14.923 - {3.692}^{2} = 1.292$

3)

$\sqrt{1.292 = 1.136}$
