1 Answer/Comment
x^2 + 11x + 24 = 0

(x + 3)(x + 8) = 0;

x + 3 = 0; x = -3;
x + 8 = 0; x = -8

x = {-3, -8}

(5x – 3.6) – (4x + 1.2)

= 5x - 3.6 - 4x - 1.2

= 5x - 4x - 3.6 - 1.2

= x - 4.8

Given the polynomial x^7 + 3x^2 - 4x^8 + 7x^3, what is the degree of the polynomial?
Weegy: x^7 + 3x^2 - 4x^8 + 7x^3, the degree of the polynomial is 8. ser: Solve for x: -4x + 7 = 35 Weegy: 4x + 7 = 35; 4x = 35 - 7; 4x = 28; x = 28/4; x = 7 User: Solve for x: -2(x-4) = -3(x + 8) Weegy: -2(x - 4) = -3(x + 8); -2x + 8 = -3x - 24; -2x + 3x = -24 - 8; x = -32 (More)
