How to factorise 6ac-12

Answers

Common is 6 so it would be 6 on the outside of the brackets.
Therefore it would be ac inside with a -2 because there is 2 6's in 12 :)
6 (ac - 2)

$6ac-12=\n6(ac-2)$

[(25-11)+(15-9)] divided by 5

Answers

Well, first of all, you have to calculate what is in the bracket first. so;
[14] + [6]
That is;
14+6=20
Since it is divided by 5, that will be 20/5
So the answer is 20/5=4
Hope i helped. Have a nice day.

pemdas so parenthasees first
25-11=14

and 15-9=6
now we have
[(14)+(6)]/5
parenthasees
add 14+6=20
[20]/5
4 the asnwer is 4

Please help thank you guys

Answers

Basically: Whenever you have a number times a variable, you don't have to write the multiplication sign.

5 × n is the same thing as 5n.

Let's write each of these out.
a) 5 + 2 + x
b) 5 + 2x
c) 5 + x + x
d) 5 + x² (the ² means multiply by itself)
e) 5 + 2x (sum = adding together)
f) 5 × 2x (product = multiplying together)

As you can see, only B and E fit the expression given.
