A board 10ft long is cut into two pieces. Four times the length of the shorter piece is 2ft less than two times the length of the longer piece. Find length of the longer piece.

7 ft

Step-by-step explanation:

Let x be the shorter and y be the longer length

x + y = 10

x = 10 - y

4x = 2y - 2

4(10 - y) = 2y - 2

40 - 4y = 2y - 2

6y = 42

y = 7

answer: the two figures are congruent.

step-by-step explanation: they're congruent because figure efgh is reflected across the x and y axis but it was also rotated.

hope it !
