The associative property<span> is when you can add and multiply no matter which way the problem is, for example, 2+4 = 6 and 6-4= 2 or 4+2= 6 </span>

Definition<span>: The </span>associative property<span> states that you can add or multiply regardless of how the numbers are grouped. By 'grouped' we mean 'how you use parenthesis'. In other words, if you are adding or </span>multiplying<span> it does not matter where you put the parenthesis. Add some parenthesis any where you like!.

I hope this helps you</span>

Factor the greatest common factor: −5k2 20k − 30. −1(5k2 − 20k 30) −5(k2 − 4k 6) −5k(k2 − 4k 6) −5(k2 4k − 6)
Leno4ka [110]

The greatest common factor−5k2 20k − 30 is  -5(k^{2} -4k-6).

<h3>What is meant by the greatest common factor?</h3>
  • The most common factor in mathematics is the highest number that may divide evenly into two other numbers.
  • The largest factor that splits both numbers is the greatest common factor. List the prime factors of each integer before calculating the greatest common factor. One 2 and one 3 are shared by those aged 18 and 24. We multiply them to obtain the GCF. Therefore the GCF for 18 and 24 is 2 * 3 = 6.
  • The biggest positive integer that divides evenly into all the numbers with no remainder is the greatest common factor (GCF, GCD, or HCF) of a collection of whole numbers.

To find the greatest common factor:

−5k2 20k − 30.

Factor the expression:   5(-k^{2} +4k-6)

Factor the expression:   5(-k^{2} -4k+6)

Multiply the monomials: 5(k^{2} +4k+6)

The greatest common factor: -5(k^{2} -4k-6).

The greatest common factor−5k2 20k − 30 is -5(k^{2} -4k-6).

In the figure below, points D, E, and F are the midpoints of the sides of LABC,
attashe74 [19]

Answers:

  • DE = 39
  • AB = 68
  • BE = 34

=============================================================

Explanation:

BC = 78 is parallel to the midsegment DE.

This parallel midsegment is half as long as BC, so DE = BC/2 = 78/2 = 39

-------

DF = 34 doubles to AB = 2*DF = 2*34 = 68, since the midsegment is half as the parallel side, so we just think in reverse of that process.

-------

BE = 34 for two reasons

  • Quadrilateral EBFD is a parallelogram with opposite sides BE and DF that are congruent.
  • E is the midpoint of AB, so BE is half as long as AB

--------

We don't use the info that AC = 48.
