зделать и кто правильно зделает получить лутшый ответ и 5 звезд и сердечко

Answer 1

$48x + 6 = 6(8x + 1)$

$5d + 5l \\ 5(d + l) \\ (l + d) \times 5$

$15 {c}^{2} {d}^{2} - 54 {c}^{2} {d}^{3} + 9 {cd}^{13} = \\ 3 {cd}^{2} (5c - 18cd + 3 {d}^{11} )$

$5 {x}^{2} - 23x = 0 \\ x(5x - 23) = 0 \\ x = 0 \\ 5x - 23 = 0 \\ 5x = 0 + 23 \\ 5x = 23 \\ x = 23 \div 5 \\ x = 4 \frac{3}{5} = 4.6$

х1=0, х2=4.6

$2.45 \times 110 - 2.45 \times 10 = \\ 2.45 \times (110 - 10) = 2.45 \times 100 = \\ 245$
