Weegy: 12z + 2b
User: Simplify 5 + 2{x - 4[3x + 7(2 - x)]}.
Weegy: (3x-2) squared is 9x^2 - 12x + 4.
User: 5 + 2{x - 4[3x + 7(2 - x)]}.
Weegy: x = 3
User: (y3 - 125) ÷ (y - 5)
Weegy: y = 31

(6a + b)^2
= (6a+b)(6a+b)
= 36a^3 + 12ab + b^2

5 + 2{x - 4[3x + 7(2 - x)]}
= 5 + 2x + 32x - 112
= (2x + 32x) + (5 + - 112)
= 34 + - 107

5 + 2{x - 4[3x + 7(2 - x)]}
= 5 + 2[x - 4(3x + 14 - 7x)]
= 5 + 2[x - 4(14 - 4x)]
= 5 + 2(x - 56 + 16x)
= 5 + 2(17x - 56)
= 5 + 34x - 112
= 34x - 107

(y^3 - 125) ÷ (y - 5)
=(y^3 - 5^3)/(y - 5)
= (y - 5)(y^2 + 5y + 25)/(y - 5)
= y^2 + 5y + 25
