Salma showed me how to do it.
Here are two ways:
8 times (5·3 - 2) = 8 times (15 - 2) = 8 times 13 = 104 .
8 times (5·2 + 3) = 8 times (10 + 3) = 8 times 13 = 104.
Thank you, Salma.
Answer:
The radius of each circle is 2.5 units
Step-by-step explanation:
Answer:
see below
Step-by-step explanation:
9 x 8 = (10 x 8) - ( blank x 8) =80 - blank = blank
We are replacing 9 with 10 minus something
9 = 10 -1
9 x 8 = (10 x 8) - ( 1 x 8)
80 - 8
72
Answer:
The factor form is 
Step-by-step explanation:
When it is required to factor the expression given in the problem, we have to first find a common term or terms, which will be found by either grouping the like terms or the splitting of the terms.
Now the expression that is given here is:

Now, here we will take:

Thus we will get:

Now we will do the middle term split as follows:

Substituting back
, we will have:

Hence, the required factor form of the given expression will be:

I think a is (8,-8)
B) (0,8)
