what is 5(2a+3) ? please I'm stuck

Thanks saseflower. 

Its nice to see you here ☺

5(2a+3)

=5×(2a+3)

=5×2a +  5×3

=10a    +  15   

5(2a + 3)

Use distributive property

10a + 15

And thats it, since you are just simplifying because there is no equal sign and numbers on the opposite side of the equal sign

Thank you Melody! I've missed the forum
