Answer 1

Ответ:

а)

$s = 6 {a}^{2} = 6 {(x - 5)}^{2} = \\ 6( {x}^{2} - 10x + 25) = \\ 6 {x}^{2} - 60x + 150 \\ б)v = {a}^{3} = {(x - 5)}^{3} = \\ {x}^{3} - 15 {x}^{2} + 75x - 125$

Answer 2

$S=6a^2; \ \ a=x-5 \\ \\ S=6\cdot(x-5)^2=6\cdot (x^2-2\cdot 5\cdot x+5^2)=6\cdot(x^2-10x+25)=6x^2-60x+150$

$V=a^3=(x-5)^3=x^3-3\cdot x^2\cdot 5+3\cdot x\cdot 5^2-5^3=x^3-15x^2+75x-125$
