Answer:
solution,
[tex]a. \: 3(x + 5) \\ \: \: = 3 \times x + 3 \times 5 \\ \: \: = 3x + 15[/tex]
[tex]b. \: 4(x - 4) \\ \: \: = 4 \times x - 4 \times 4 \\ \: \: = 4x - 16[/tex]
[tex]c. \: 2(5x + 1) \\ \: = 2 \times 5x + 2 \times 1 \\ \: \: = 10x + 2[/tex]
[tex]d . \: 7(x - 9y) \\ \: = 7 \times x - 7 \times 9y \\ \: \: = 7x - 63y[/tex]
Hope this helps..
Good luck on your assignment..
Answer:
a) 3(x + 5) =
= 3x + 15
b) 4(x-4) =
= 4x - 16
c) 2(5x + 1) =
= 10x + 2
d) 7(x-9y) =
= 7x - 63y
