Answer:
[tex] \huge{ \fbox{ \sf{25x + 55}}}[/tex]
Step-by-step explanation:
[tex] \star{ \sf{ \: \: 10(x + 4) + 15(x + 1)}}[/tex]
[tex] \text{Step \: 1 \: : Distribute \: 10 \: through \: the \: parentheses}[/tex]
[tex] \mapsto{ \sf{10x + 40 + 15(x + 1)}}[/tex]
[tex] \text{Step \: 2 \: : Distribute \: 15 \: through \: the \: parentheses}[/tex]
[tex] \mapsto{ \sf{10x + 40 + 15x + 15}}[/tex]
[tex] \text{Step \: 3 \: : Collect \: like \: terms}[/tex]
[tex] \text{Like \: terms \: are \: those \: which \: have \: the \: same \: base}[/tex]
[tex] \mapsto{ \sf{10x + 15x + 40 + 15}}[/tex]
[tex] \mapsto{ \sf{25x + 40 + 15}}[/tex]
[tex] \text{Step \: 4 \: : Add \: the \: numbers : 40 \: and \: 15}[/tex]
[tex] \mapsto{ \sf{25x + 55}}[/tex]
Hope I helped!
