Answer:
The equivalent expression is [tex]28p+14q+21r[/tex]
Step-by-step explanation:
The distributive property says for any numbers a, b c, and d
[tex]d*(a+b+c)=a*d+b*d+c*d[/tex]
which basically says you should multiply the coefficient [tex]d[/tex] by every term in the parenthesis to get an equivalent expression.
Applying the distributive proper to the expression [tex]7(4p+2q+3r)[/tex] we get:
[tex]7(4p+2q+3r)=7*4p+7*2q+7*3r[/tex]
[tex]=\boxed{28p+14q+21r}[/tex]
which is an equivalent expression to [tex]7(4p+2q+3r)[/tex].
