Which of the following equations has no real solutions? a. 2x - 4 = 8x - 4 b. 2(x - 4) = 2x - 8 c. 2(x + 4) = 2(x + 14) d. 2x - 4 = 2x - 4

Kylie explained that (-4x+9)^2 will result in a difference of squares because (-4x+9)^2 (-4x+9)^2 =(-4x)^2+(9)^2=16x^2+81

Which expression gives the area of the triangle shown below

Arefrigeration system at your company uses temperature sensors fixed to read celsius (°c) values, but the system operators in your control room understand only the fahrenheit scale. you have been asked to make a fahrenheit (°f) label for the high temperature alarm, which is set to ring whenever the system temperature rises above –10°c. what fahrenheit value should you write on the label
