Answer: D
Step-by-step explanation: You just have to take the equation in the question and simplify it. -2 x y = -2y, -2 x -8 = +16, so -2y + 16, then on the other side add 10 to 15 15+10=25, and then keep the -y, so finally the final equation/inequality is -2y + 16 <u><</u> 25 - y.

<span>Standard deviation for mean of n objects = (square root n) x s.d. for one
object.
So you need (2.8/0.5)^2 or around 32.</span>
Simplifying that would be 3 * (-7) -10+25 = -6. Combining like terms will get us to -21 +15 = -6, going further will be -6 = -6. Remember Order of Operations. Since -6 = -6, the equation is true.
Answer:
20x^6
Step-by-step explanation:
1. Multiply 5 and 4 to get coefficient
2. add the exponents ( 3+3) and the final exponent is 6
The final answer is 
3x-8 if this is linear and you assume that the "height" is also measured in centimeters
