(3x - 4)(2x^2 + 2x - 1) = 3x(2x^2 + 2x - 1) - 4(2x^2 + 2x - 1) = (6x^3 + 6x^2 - 3x) - (8x^2 + 8x - 4) = 6x^3 + 6x^2 - 3x - 8x^2 - 8x + 4 = 6x^3 - 2x^2 - 11x + 4
Answer:
Step-by-step explanation:
Given 30 cupcakes:
Mint icing on one fifth of the cupcakes = 30/5 = 6 cupcakes
Chocolate on one half of the cupcakes = 30/2 = 15 cupcakes
The rest will get vanilla icing = 30 - 6 - 15 = 9 cupcakes
Applying the equation for the area of the trapezoid, it is found that the height is of 10 cm.
The <em>area of a trapezoid</em> is <u>half the multiplication of the sum of the bases and the height</u>, that is:

For this problem, we have that:
, hence:





The height is of 10 cm.
