Product A sells 3.5 times more than Product B. Product B sells 40% less than Product C. Product C sold 39,000 units this month.
Rashid [163]

Answer:

81,900 units of Product A

Step-by-step explanation:

Product C:  39,000

Product B:  [39,000 - (39000 x .40)] = 39,000 - 15,600 → 23,400

Product A:  23,400 x 3.5 = 81,900

Factor this expression completely, then place the factors in the proper location on the grid.
andreev551 [17]

Notice that you have a difference of cubes:

\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2\right)^3-\left(\dfrac y3\right)^3

which can be factored using the rule,

a^3-b^3=(a-b)(a^2+ab+b^2)

So,

\dfrac{x^3}8-\dfrac{y^3}{27}=\left(\dfrac x2-\dfrac y3\right)\left(\dfrac{x^2}4+\dfrac{xy}6+\dfrac{y^2}9\right)

and just to make things look nicer, we can pull out 1/6 from the first factor and 1/36 from the second to get

\dfrac{x^3}8-\dfrac{y^3}{27}=\dfrac1{216}(3x-2y)(9x^2+6xy+4y^2)

  • Left to Right

<u>Algebra I</u>

  • Function Notation

Step-by-step explanation:

<u>Step 1: Define</u>

f(x, y) = 2x - 3y + xy²

(3, -1) is x =3 and y = -1

<u>Step 2: Evaluate</u>

  1. Substitute:                    f(3, -1) = 2(3) - 3(-1) + 3(-1)²
  2. Exponents:                   f(3, -1) = 2(3) - 3(-1) + 3(1)
  3. Multiply:                        f(3, -1) = 6 + 3 + 3
  4. Add:                              f(3, -1) = 9 + 3
  5. Add:                              f(3, -1) = 12
