You would do 20-17.08, because that is how much he got back. which is 2.92. Then you divide that by 2 since there were 2 cards which gives you 1.46 which is your answer

Here's the solution :

\qquad \sf  \dashrightarrow \:(2 {x}^{2}  + 5x - 7) + (3 - 4 {x}^{2}  + 6x)

\qquad \sf  \dashrightarrow \: 2{x}^{2}  + 5x   - 7 + 3 - 4 {x}^{2}  + 6x

\qquad \sf  \dashrightarrow \:2 {x}^{2}  - 4 {x}^{2}  + 5x + 6x - 7 + 3

Which triangles are congruent? How do you know?
choli [55]
Use the side lengths! C and D have lengths of 3 and heights of 4.
Also use how far away they are from the axis.

Both C and D are 2 away from each axis on the end point.
This also goes with A.
However, B does not seem to be congruent in the sense of (coordinates)
It is the same length and height.
