4 times 7 = 28 2( 4 times 7 ) = 2 times 28 = 56. I hoped I helped. XOXO W T F you don't know :(
You can use 2*8 to find 4*8 by solving 2*8, then multiplying it by 2. This is equivalent to 4*8, or 32.
The "multiplication facts" may be numbered differently in different textbooks, so it is really hard to guess what multiplication facts you are talking about. Better use the standard names, for example, "commutative property", "associative property", etc. For a multiplication such as 3 x 7, you either memorize the tables, your you do the repeated addition (3 x 7 = 7 + 7 + 7, that is, 7 appears 3 times as an addend.)
9*2*19 18*19
since 4 is 2 times 2 just double 7 twice: 7 doubled = 14 and then 14 double = 28
4 times 7 = 28 2( 4 times 7 ) = 2 times 28 = 56. I hoped I helped. XOXO W T F you don't know :(

4x7=28 2(4x7)=2x28=56
You cannot use a false statement (2 x 20 = 180) to find any true value.
1 x 7 plus 2 x 7 is the same as 3 x 7
base times height. take that awnser and divide it by 2. bxh 2
how can you use facts to find 6x9

2 times length times 2 times width
Use the formula: 2X3.14Xr2Xh + 2X3.14XrXh it may be confusing, because it is long 2 times pi time radius squared times height plus 2 times pi times radius times height.
9*2*19 18*19
You can use 4x7 to find 8x7 because 4 x 2 is 8, and you are simply doubling one of the numbers you are multiplying, (4 to 8) and so multiply your answer from 4x7 by 2 to get the answer to 8x7. 4x7 is 28 and 8x7 is 56, and 28 x 2 is 56.
