For this case we have the following expression:
[tex]4 (3a + 7) +3 (2a + 5)[/tex]
We must evaluate the expression for the following value:
[tex]a = 5[/tex]
We have then:
[tex]4 (3 (5) +7) +3 (2 (5) +5)[/tex]
Then, rewriting the expression we have:
[tex]4 (15 + 7) +3 (10 + 5)\\4 (22) +3 (15)\\88 + 45\\133[/tex]
Answer:
The expression for a = 5 is given by:
[tex]4 (3a + 7) +3 (2a + 5) = 133[/tex]
