Let's check the sets

  • A={2,4,6,8,..}
  • B={3,6,9..}
  • C={7,14,21..}

Find LCM

  • 2×3×7=42

  • (AnBnC)={42}

Recreate the sets

  • A={2,4,6,8,10,12..,42}
  • B={3,6,9,..,42}
  • C={7,14..42}

Now

  • n(A)=21
  • n(B)=14
  • n(C)=6

Hence

Universal Set =U

\\ \sf\longmapsto U\in R^{+}-\{2,3,4,6,7,8,9,12,14,15,16,18,20,21,22,24,25,26,27,28,30,32,33,34,35,36,38,39,40 ,42\}

What is the factorization of 3x2 – 8x + 5?
tatuchka [14]

For this case we must factor the following expression:

3x ^ 2-8x + 5

We rewrite the middle term as a sum of two terms whose product is

a * c = 3 * 5 = 15

And whose sum is

b = -8

These numbers are:

-5 and -3

So:

3x ^ 2-5x-3x + 5

We factor the maximum common denominator of each group:x (3x-5) - (3x-5)

We take common factor(3x-5):

(3x-5) (x-1)

Answer:

(3x-5) (x-1)

Hi what is the answer for this?
saw5 [17]
This is a common factor problem.

Pencils come in a pack of 12
Erasers come in a pack of 10

First, break the number into their prime factors(the idea is that we will break the number down into its smallest multiples, which are prime numbers):
10 = 2 * 5
12 = 2 * 2 *3

So now we take the unique multiples of each number, and when we multiply them together, we will get the smallest number that both 10 and 12 can be divided into(this is what the problem is asking for)
We have (2*2*3) that comes from 12, and the only unique number that comes from the 10 is (5)
So now, we multiply:
2*2*3*5=60
However, this isn't exactly out answer. Now we have to divide our answer by the number of each this in the pack to know how many packs to buy.
60/12=5 packs of pencils
60/10= 6 packs of erasers

I hope this helps. Let me know if you have any questions!!

What is the value of c?<br> O 4 units<br> O 5 units<br> O 6 units<br> O 7 units
Aleksandr [31]

The value of c is 5 units.

Step-by-step explanation:

Given,

WY = a =  4

ZY = b = 3

As WYZ is forming a right angle triangle, therefore, we can use pythagorean theorem to find the value of c

a^2+b^2=c^2\\(4)^2+(3)^2=c^2\\16+9=c^2\\c^2=25

Taking square root on both sides

\sqrt{c^2}=\sqrt{25}\\c=5

The value of c is 5 units.
