You can use the fact that 4 is equal to 2 times 2 and the fact that 9 can be expressed as 3 times 3. By multiplying these facts, you can calculate 4 times 9 as follows: 4 times 9 equals (2 times 2) times (3 times 3). This can be rearranged to (2 times 3) times (2 times 3), which simplifies to 6 times 6, giving you 36 as the answer.
To find (4 \times 12), you can break it down using the 10s and 2s facts. First, recognize that (12) can be expressed as (10 + 2). Then, use the distributive property: (4 \times 12 = 4 \times (10 + 2) = (4 \times 10) + (4 \times 2)). This gives you (40 + 8 = 48), so (4 \times 12 = 48).
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.
You can leverage multiplication facts with smaller numbers to help remember those for 11 and 12 by recognizing patterns. For instance, when multiplying by 11, you can break the multiplication into smaller parts; for example, ( 11 \times 4 ) can be thought of as ( 10 \times 4 + 1 \times 4 = 40 + 4 = 44 ). For 12, you can use ( 12 \times n ) as ( 10 \times n + 2 \times n ); for example, ( 12 \times 5 = 10 \times 5 + 2 \times 5 = 50 + 10 = 60 ). By mastering these smaller calculations, you can more easily derive the larger products.
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.)

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.
