21 not sure but you can do it
Answer:
If a number is a multiple of 2, it may NOT be a multiple of 4. An example would be the number 6.
, but
.
However, if a number is multiple of 4, it is guaranteed to be a multiple of 2, since 4 itself is a multiple of 2.
Example:

This is simply
.
It is a multiple of 2 twice.
Answer:

Step-by-step explanation:
Step 1: Factor
g = a(H + n)
Step 2: Divide both sides by expression in parenthesis
g/(H + n) = a
The missing digit is number 3. The total amount should be $132
I multiplied 11 by the numbers 10 and above to get the possible three digit answer who has 1 as the first digit and 2 as the last digit.
11 x 10 = 110
11 x 11 = 121
11 x 12 = 132
The 11 members of the Middle School Math club each paid $12 for a guest speaker.
Answer:
6 miles
Step-by-step explanation:
The distance formula is expressed as;
D = √(x2-x1)²+(y2-y1)²
D = √(2-4)²+(8-2)²
D = √(-2)²+(6)²
D = √4 + 36
AD = √40
AD = 6.32
Hence the approximate distance between the library and the mall is 6 miles
