B) The length of the rectangle below is (2x - 1) cm and its width is (x + 3) cm.
(2x - 1)
(r + 3)
(i)
Write an expression in the form ax2 + bx + c for the area of the rectangle.
Given that the area of the rectangle is 294 cm?, determine the value of x.
(iii)
Hence, state the dimensions of the rectangle, in centimetres.

Create a question with this scenario you could ask that could be answered only by graphing or using logarithm. david estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x.

Is there a direction u in which the rate of change of f(x, y)equals=x squared minus 3 xy plus 4 y squaredx2−3xy+4y2 at p(1,2) equals 14? give reasons for your answer. choose the correct answer below. a. no. the given rate of change is smaller than the minimum rate of change. b. no. the given rate of change is larger than the maximum rate of change. c. yes. the given rate of change is larger than the minimum rate of change and smaller than the maximum rate of change.
