Please choose an answer below. A) ∠2 is the only angle of elevation; ∠3 is the only angle of depression B) ∠1 is the only angle of elevation; ∠4 is the only angle of depression C) ∠1 and ∠2 are angles of elevation; ∠3 and ∠4 are angles of depression D) ∠2 and ∠4 are angles of elevation; ∠1 and ∠3 are angles of depression

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".

it is b)

hope this : )

step-by-step explanation:

26?

step-by-step explanation:

step-by-step explanation:   divide the numerator by the denominator to get the decimal

it would still be 193

if divide by 100 then 1.93

i am not sure
