Question 67450
Rewrite, using the distributive property:
A. 5(7+6) = 5*7+5*6 = 36+30 = 65
B. 15+7(10+5) = 15+7*10+7*5 = 15+70+35 = 120
C. 13-6(9+4) = 13-(6*9+6*4) = 13-(54+24) = 13-78 = -65
D. -3(8+7) = -3*8 + (-3)*7 = -24 + (-21) = -45
E. 4-6(8-12) = 4-(6*8-6*12) = 4-(48-72) = 4-(-24) = 4+24 = 28 
F. 6(4-9)+7(5+7) = (6*4-6*9) + (7*5+7*7) = (24-54)+(35+49) = (-30)+(84) = 54
