Answer: 6(4a\cdot2)=(6\cdot4a)\cdot2

Step-by-step explanation:

The associative property of multiplication says that when we multiply three or more than three real numbers, the product is always the same nevertheless of their regrouping by using parenthesis.

i.e. a\cdot(b\cdot c)=(a\cdot b)\cdot c

Hence, the right option is 6(4a\cdot2)=(6\cdot4a)\cdot2

Answer:

b

Step-by-step explanation:

Given

x³ + 5x² - 9x - 45 ( factor the first/second and third/fourth terms )

= x²(x + 5) - 9(x + 5) ← factor out (x + 5) from each term

= (x + 5)(x² - 9) ← factor as a difference of squares

= (x + 5)(x - 3)(x + 3)

The equation of the parabola is:

y = 24x^2

---------------------------

The <em>equation </em>of a parabola of vertex (h,k) and focus (0,f) is given by:

y = 4p(x - h)^2 + k^2

  • Vertex at the origin means that h = 0, k = 0.
  • Focus (0,6) means that p = 6

Thus, the equation of the parabola is:

y = 4p(x - h)^2 + k^2

y = 4(6)(x - 0)^2 + 0^2

y = 24x^2

Which of the following is equal to 5/8÷2/7?
natta225 [31]

Answer:

5/8 * 7/2

Step-by-step explanation:

Whenever you divide fractions, you can use the 'keep change flip' method.

You keep 5/8, change the division sign to multiplication, and then flip the second fraction.

1. 5/8 / 7/2  -  Keep 5/8

2. 5/8 * 7/2  -  Change division sign

3. 5/8 * 2/7  -  Flip the second fraction, 7/2 -> 2/7
