Which of these numbers are multiples of 18? select all correct answers. (a) 35691 (b) 123456 (c) 654321 (d) 102030 (e) 235910

1,2,3,6,9,18

Step-by-step explanation:

The multiples of 18 are 1,2,3,6,9,18 or 1*18, 2*9, and 3*6. 5 is not so that eliminates A,B,C and E But 0 or 10, 20, and 30 aren't either.

They all are incorrect

Step-by-step explanation:

To find the multiples of a number, just divide!

for ex.  21 is the number you are asked to find the multiples for

A) 234567

B) 6757587

C) 56788901

D) 21

E) 2345678910

You have to divide each number by 21. If there is a positive (non-decimal) quotient, then that number is a multiple of 21. (Example; 21 divided by 21 is 1! 1 is a positive and non-decimal number. So, 21 is a multiple of 21)

These same rules can be used for 18 too.

35691 divided by 18 =    1982.83333333    (NOPE)

123456 divided by 18 =    6858.66666667   (NOPE)

654321 divided by 18 =    36351.1666667    (NOPE)

102030 divided by 18 =     5668.33333333   (NOPE)

235910 divided by 18=      13106.1111111    (NOPE)

So, all of them are incorrect

he used the algebra tiles correctly.

step-by-step explanation:

given : 3x(2x-1)

solution :

since he used algebra tiles .

armando's solution is the same in the solution shown in figure

as he distributed 2x into x and x and wrote them vertically

and also write   -1 vertically

and 3x into x and x and x and wrote it horizontally

performing the multiplication in the algebra tiles we get

and solving the given expression :

3x(2x-1)

since solving the expression using tiles   and solving the expression algebraically we get the same answer

thus   we can choose the first statement as the answer to this problem which is "he used the algebra tiles correctly".
