You will need 7 because 150 divided by 20 is 7
Answer:
this is really confusing but i will see if i can find anything
Step-by-step explanation:
(2x + y)³
(2x + y)(2x + y)(2x + y)
(2x(2x + y) + y(2x + y))(2x + y)
(2x(2x) + 2x(y) + y(2x) + y(y))(2x + y)
(4x² + 2xy + 2xy + y²)(2x + y)
(4x² + 4xy + y²)(2x + y)
4x²(2x + y) + 4xy(2x + y) + y²(2x + y)
4x²(2x) + 4x²(y) + 4xy(2x) + 4xy(y) + y²(2x) + y²(y)
8x³ + 4x²y + 8x²y + 4xy² + 2xy² + y³
8x³ + 12x²y + 6xy² + y³
Decide whether the two figures are similar. . Triangle A: (1,4), (3, 5), (4,2) Triangle B: (0, 5), (4,7), (6, 1)

Answer:
Step-by-step explanation:
triangle A sides
√((5 - 4)² + (3 - 1)²) = √5
√((5 - 2)² + (3 - 4)²) = √10
√((4 - 1)² + (2 - 4)²) = √13
triangle B sides
√((7 - 5)² + (4 - 0)²) = √20 = 2√5
√((7 - 1)² + (4 - 6)²) = √40 = 2√10
√((6 - 0)² + (1 - 5)²) = √52 = 2√13
As each leg of B is twice a leg of A, they are similar
First we can either add 19 and 11, or we can do this another way.
19 + 11 = 30 To find how much thirty tens are, just add a 0 on the end of 30: 300
The other longer way to do it is: add a 0 to 19: 190, then add a 0 to 11: 110
110 + 190 = 300
There is your answer!
