29. 0.4(3d-5)
Multiply the bracket by 0.4
(0.4)(3d)(0.4)(-5)
= 1.2d-5
32). 2(3a+2)
(2)(3a)(2)(2)
=6a+4
35. 2/5(5k+35)-8
Cross out 5 and 5 for 2/5k, divide by 5. Then becomes 2k
Cross out 35 and 5, divide by 7. 35/7=5 5/5=1
2k+14-8
=2k+6
38. 1/2(12n-8)
Cross out 2 and 12, divide by 2 and then becomes 6n. Cross out 2 and 8, divide by 2 and then becomes -4
= 6n-4
