Answer:
Explanation:
Multiply the figure outside the bracket with each figure inside the bracket, and also be cautious of the signs.
1) -5(x + 2)
= -5x - 10 (multiply -5 with x and then multiply it with +2)
3) 7(1-9x)
= 7 - 63x (multiply 7 with 1 then multiply it with 9x)
5) 9(8 - 8a)
= 72 - 72a (multiply 9 with 8 then multiply it with 8a)
7) 4n - 7n
= -3n (subtract the numbers only, as both are being multiplied with n, they can be subtracted)
9) n - 2 + 6
= n + 4
