X = 3 and CB = 19. To find x you would put 4x-9 + 3x+5 = 17. Remember to get all the x’s on one side and the other numbers on the other aide of the equal sign. Then plug x into the length of BC.
1) 8^3/4 = 4th root (8^3) (top row, third one)
2) 7^2/3 = ∛7^2 (second row, third one)
3) 3^4/3 = ∛3^4 (second row, first one)
4) 25^3/4 = 4th root (25^3) (first row, first one)
5) 44^3/2 = √44^3 (third row, first one)
