The work of a student to find the dimensions of a rectangle of area 6 + 8x and width 2 is shown below:

step 1: 6 + 8x
step 2: 2(4) + 2(6x)
step 3: 2(4 + 6x)
step 4: dimensions of the rectangle are 2 and 4 + 6x

in which step did the student first make an error and what is the correct step?
step 3; 2 + (4 + 6x)
step 3; 2 + (4 ⋅ 6x)
step 2; 2(4) + 2(4x)
step 2; 2(3) + 2(4x)

Sanya noticed that the temperature was falling at a steady rate of 1.4 degrees every hour from the time that she first checked her outdoor thermometer. by 6 a. m., the temperature had fallen 21 degrees. which expression can you use to find how many hours earlier she had first checked the thermometer?

You have learned about the six trigonometric functions, their definitions, how to use them, and how to represent them graphically. the sine, cosine, and tangent trigonometric functions can be paired with their reciprocal functions, cosecant, secant, and cotangent, respectively. think about how each function is related to its reciprocal function. how are the graphs of the reciprocal functions related to their corresponding original functions? what happens to the graphs of the reciprocal functions as x approaches the zeros of the original functions? describe how you would teach friends with different learning styles (visual-spatial, aural-auditory, verbal-linguistic, physical-bodily-kinesthetic, logical-mathematical, social-interpersonal, and solitary-intrapersonal) how to graph the reciprocal functions
