Multiply (2.4 ⋅ 1014) ⋅ (4 ⋅ 107). express the answer in scientific notation. 9.6 ⋅ 1021 9.6 ⋅ 1022 96 ⋅ 1021 96 ⋅ 1022

9.6 × .

Step-by-step explanation:

Given : Multiply .

To find :  Express the answer in scientific notation.

Solution : We have given that

.

Combine the like terms

(2.4 * 4 )( .

By the exponent same base rule : if the base of two exponent are same then exponent will be add.

9.6 × .

9.6 × .

Therefore, 9.6 × .

what are the things "represented below"?

step-by-step explanation:

nobody can if you dont give the choices

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".
