Need to correct these for my quiz: (no blank answers please)

<WYV = 64

<VYX = 104

Step-by-step explanation:

Angle WYV is across from SYT, and SYT is 64, since the lines intersect, it becomes clear that WYV is also, 64.

Angle VYX is vertical from angle SYU, which is equivalent to both SYT and TYU combined, thus, the answer would be both those angles combined (64 + 40) which brings us to the conclusion that VYX is equivalent to 104.

Hope this helps!

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".
