Answer 1

Answer:

23) 36·(3·1/4) = 36·(3/4) = 108/4 = 27

24) (4·2/7)·21 = (8/7)·21 = 168/7 = 24

25) 2(x+4) = 2x+8

26) (5+n)3 = 15+3n

27) (4-3m)8 = 32-24m

28) -3(2x-6) = -6x+18

29) 13r+5r = 18r

30) 3x³-2x²

31) 7m+7-5m = 2m+7

32) 5z²+3z+8z² = 3z+13z²

33) (2-4n)17 = 34-68n

34) 11(4d+6) = 44d+66

35) 7m+2m+5p+4m = 13m+5p

36) 3x+7(3x+4) = 3x+21x+28 = 24x+28

37) 4(fg+3g)+5g = 4fg+12g+5g = 4fg+17g

38) (5m)²+(m+5)²= 26m²+10m+25

39) 7(a²+b)-4(a²+b) = 3(a²+b) = 3a²+b
