-12y - 8x - 4x = -12y - 12x

x^2 - 4y^2 - xy, when x = 2, y = -2;

(2)^2 - 4(-2)^2 - (2)(-2);

4 - 4(4) - (-4);

4 - 16 + 4

-12 + 4 = -8

Weegy: answer: x= -5. User: Add. (8x + 8) + (6x - 4) Weegy: answer: x= -5. User: Subtract. (5x7 - 16x5 - 11) - (-11x5 + 9x7 - 14) Weegy: answer would be -50 User: Evaluate. (-9)0 Weegy: The answer is 1. Anything to the power of 0 will equal 1. Try it on your calculator. User: Simplify. (82)-4 Weegy: 1/16777216 User: Multiply. (-0.8x6)(-0.9x5) Weegy: The correct answer is 0.72x^11. User: Multiply. 9(7x - 8) Weegy: answer: x= -5. User: Multiply. (9m + 10)2 (More)

(8x + 8) + (6x - 4) = 14x + 4
(5x^7 - 16x^5 - 11) - (-11x^5 + 9x^7 - 14)

= -4x^7 - 5x^5 + 3
(-0.8x^6)(-0.9x^5) = 0.72x^11
9(7x - 8) = 63x - 72
(9m + 10)^2;

(9m + 10)(9m + 10);

81m^2 + 90m + 90m + 100

= 81m^2 + 180 + 100
