The first few steps in solving the quadratic equation 5x2 + 27x = 14 − 13x by completing the square are shown. 5x2 + 27x = 14 − 13x 5x2 + 40x = 14 5(x2 + 8x) = 14 Which is the best step to do next to solve the equation by completing the square? 5(x2 + 8x + 16) = 30 5(x2 + 8x + 16) = 94 5(x2 + 8x + 4) = 18 5(x2 + 8x + 4) = 34

question is incomplete.

the surface area is 124cm²

step-by-step explanation:

length: 4cm

width: 9cm

height:   2cm

the functions have the same rate of change i think. i narrowed it down to this answer and "the rate of change of tour 1 is greater" but i got it wrong using that answer so im assuming its the answer above. (this is a question i also answered from the iready site if anyone needs a reference)
