Is 32643 divisible by both 3 and 9? why or why not

Yes it is. It is divisible by both numbers because the sum of the digits that make up the number gives a multiple of 3 and 9.

Step-by-step explanation:

For a number to be divisible by 9, the sum of all the digits that make up that number must give a multiple of 9. If the number is divisible by 9, it is divisible by 3 as 3 is a factor of 9. Also, For a number to be divisible by 3, the sum of all the digits that make up that number must give a multiple of 3.

Therefore to know if 32643 is divisible by 9,

3 + 2 + 6 + 4 + 3 = 18

Since 18 is a multiple of 9, then 32643 is divisible by 3 and 9.

answer: bearing in mind that a rectangle has a perimeter of length + length + width + width.

step-by-step explanation:

p = perimeter

l = length

x=width

p = 2l + 2x

p = 2(l+x)     < ==== perimeter of the base of the box.

sas (side angle side)

aa (angle angle)

sss(side side side)

sas find two sides with an angle in between

aa is finding two angles and the third will add up to 180

sss find all sides
