To obtain the distributed Expression
A.
4(x + 3)
We will expand by multiplying each term in the bracket by 4
=> 4 X x + 4 X 3
=> 4x + 12
B.
5 (2 + 10m + 4)
WE will also multiply each term by 5
=> 5 X 2 + 5 X 10m + 5 X 4
=> 10 + 50 M + 20
Upon collecting like terms to simplify the expression
=> 50M + 30
C.
a (8 + a) + 3a
[tex]\begin{gathered} we\text{ will expand the term in the bracket by multiplying by a} \\ a\text{ x 8 + a x a + 3a} \\ 8a\text{ + }a^2\text{ + 3a} \end{gathered}[/tex]
We then Re-arrange by collecting like terms
[tex]\begin{gathered} a^2+8a\text{ +3a} \\ a^2+\text{ 11a} \end{gathered}[/tex]
