Answer:
a. 2
b. 8(-4)
c. (37)
d. (60 + 8)
Step-by-step explanation:
This just shows how to expand brackets. So to expand 2(9+4) you would, do 2*9 + 2*4 and same for b.
Part d is a little different because it can be any two numbers that add up to 68 (here I just put the most simple one I could think of).
b. 8, 4
c. 37
d. 60 + 8
[tex]a.\ 2(9+4) = 2*9 + 2*4[/tex]
[tex]b.\ 8(7-4) = 8(7) - 8(4)[/tex]
[tex]c.\ 8(30 + 7) = 8(37)[/tex]
[tex]d.\ 6(60 + 8) = 6(68)[/tex]
