Объяснение:
S=6a^2, S=(x-4)^2=x^2-8x+16
V=a^3, V=(x-4)^3=x^3-3*x^2*4+3*x*4^2-4^3), V=x^3-12x^2+48x-64
a) S = 6a²
a = x - 5
S = 6(x - 5)² = 6(x² - 10x + 25) = 6x² - 60x + 150
S = 6x² - 60x + 150
б) V = a³
a = x - 5
V = (x - 5)³ = x³ - 3 * x² * 5 + 3 * x * 5² - 5³ = x³ - 15x² + 75x - 125
V = x³ - 15x² + 75x - 125
