Answer:
-x-15
Step-by-step explanation:
x-2x-15
1x-2x-15 (if a term doesn't have a coefficient then the coefficient is 1)
(1-2)x-15 (collect like terms by subtracting their coefficients)
-1x-15
-x-15 (when the term has a coefficient of -1, the number doesn't have to be written but the sign remains)
A right rectangular prism would have three pairs of identical sides. You need to find the area of each of these sides individually, then add them to find the total surface area of the shape.
The dimensions of the three unique of sides are length x width, width x height, and height x length.
So:
2(6 * 9) + 2(9 * 10) + 2(10 * 6)
2(54) + 2(90) + 2(60)
108 + 180 + 120
= 408 inches^2

I cant tell whether the X is a multiplication sign or not, enjoy.Simplifying 4x + -1(9) * 103 + -5x2 = (-14) Multiply -1 * 9 4x + -9 * 103 + -5x2 = (-14) Multiply -9 * 103 4x + -927 + -5x2 = (-14) Reorder the terms: -927 + 4x + -5x2 = (-14) -927 + 4x + -5x2 = -14 Solving -927 + 4x + -5x2 = -14 Solving for variable 'x'. Reorder the terms: -927 + 14 + 4x + -5x2 = -14 + 14 Combine like terms: -927 + 14 = -913 -913 + 4x + -5x2 = -14 + 14 Combine like terms: -14 + 14 = 0 -913 + 4x + -5x2 = 0 Begin completing the square. Divide all terms by -5 the coefficient of the squared term: Divide each side by '-5'. 182.6 + -0.8x + x2 = 0 Move the constant term to the right: Add '-182.6' to each side of the equation. 182.6 + -0.8x + -182.6 + x2 = 0 + -182.6 Reorder the terms: 182.6 + -182.6 + -0.8x + x2 = 0 + -182.6 Combine like terms: 182.6 + -182.6 = 0.0 0.0 + -0.8x + x2 = 0 + -182.6 -0.8x + x2 = 0 + -182.6 Combine like terms: 0 + -182.6 = -182.6 -0.8x + x2 = -182.6 The x term is -0.8x. Take half its coefficient (-0.4). Square it (0.16) and add it to both sides. Add '0.16' to each side of the equation. -0.8x + 0.16 + x2 = -182.6 + 0.16 Reorder the terms: 0.16 + -0.8x + x2 = -182.6 + 0.16 Combine like terms: -182.6 + 0.16 = -182.44 0.16 + -0.8x + x2 = -182.44 Factor a perfect square on the left side: (x + -0.4)(x + -0.4) = -182.44 Can't calculate square root of the right side. The solution to this equation could not be determined
