Step-by-step explanation:
hello,
you just need to multiply all values inside the brackets with the value outside the bracket and then work it out as normal.
for instance,
a) 4( x + 3)
= 4x + 12
here you can see i multiplied both values by 4.
b) 4(x - 5)
= 4x - 20
c)2(x + 2)
= 2x + 4
d) 4(1 - c)
= 4 - 4c
hope this makes things clearer for you! thank you!
