You should try the distributive property of multiplication:

3(2x+7)

3 x  2x = 6x

3 x 7 = 21

Therefore:

6x + 21

Answer:

6x+21 (Maybe)

Are you doing the buddy method, how is your teacher wanting to do this, When you respond I might have the correct answer

(buddy method) Multiply the 2x and 7 by the 3 giving you 6x+21 and then that's it you cant do anything else but I don't know if that's how you're teacher wants it done.

Please help with the following maths question
zavuch27 [327]

Answer:

120 degrees

Step-by-step explanation:

Regular hexagon means all the sides are equal

(6-2)(180)=The sum of interior angles of hexagon

=>720 degree

Therefore each angle=720/number of sides

=720/6=120 degree

So let the marked angle in figure be 'x'

And the adjacent equal angles to x, y

So y+y+x=360 [Angle around point=360]

2y+x=360 [but y=120 degree proved]

240+x=360

x=120

There are ten pennies 14 nickels and 6 dimes in a bag and you remove 3 at a random without replacing any what is the probability
Tatiana [17]
There are 10+14+6=30 total coins in the bag including 10 pennies,14 buckles and 6 dimes
Then,
P(removing a penny after first pick):
10/30 or 1/3
Now, there are only 9 pennies, and total amount of coins decrease by one count which is 29
P(remove a nickel after second pick):
14/29
Now, there are only 28 coins in total left in the box, so
P(removing a dime):
6/28 or 3/14
Lastly, to find the probability or compound event, take:
1/3×14/29×3/14=42/1638
Simplify 42/1638
21/819. As a result, the probability you remove a penny and nickel and a dime in that order is 21/819. Hope it help!
