Answer:

  $1000

Step-by-step explanation:

If we assume that the given average applies to April, May, and June expenses, then we can use the formula for average to find June's expenses.

  average expenses = (April +May +June)/3

  940.21 = (945.50 +875.13 +June)/3

  (3)(940.21) = 1820.63 +June

  2820.63 -1820.63 = June = 1000.00

Rob's expenses in June were $1000.00.

She gives 1/6 to Lucinda (it says in the problem??).

She starts with 17 tonnes. She loses 1/6.
17 - 1/6 = 16 5/6
Gwendoline has 16 5/6 tonnes of jam left.

What are the roots of the polynomial equation? –3, –2, 3 –3, 2 18, 32 18, 32, 66
inn [45]

The root of the polynomial function x^3 - 2x^2 + 5x - 6 = -4x^2 + 14x + 12 is -3, -2 and 3

<h3>How to determine the roots of the equation?</h3>

The graph that completes the question is added as an attachment

The polynomial function is given as:

x^3 - 2x^2 + 5x - 6 = -4x^2 + 14x + 12

From the attached graph, we have the following highlight:

The curves of both equations intersect at

x = -3, x = -2 and x = 3

This means that the root of the polynomial function is -3, -2 and 3

Hence, the root of the polynomial function x^3 - 2x^2 + 5x - 6 = -4x^2 + 14x + 12 is -3, -2 and 3
