Determine the measures of the unknown angles in the figure. m < APD =

m < CPE =

m < BPD =

angle APD=115 degrees

angle CPE=25 degrees

angle BPD=65 degrees

Step-by-step explanation:

APD=180-65=115 because it is supplementary

CPE=90-65=25 because it is complementary

BPD=65 because it is an alternate angle

m < APD =115

m < CPE =25

m < BPD =65

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".

hi there!

the answer to this question is d: 35

step-by-step explanation:

5 to the power of 2 is 25

2 multiplied by 5 is 10

then you add the 2 numbers and you get 35
