In this question it is given that
[tex] \lim_{x->-5}f(x)=17, \lim_{x->-5}g(x)=22 [/tex]
And we have to find the value of the given limit
[tex] \lim_{x->-5}(23f(x)+3g(x)) [/tex]
Using properties of limit, first we separate the two functions, that is
[tex] 23\lim_{x->-5}f(x)+3\lim_{x->-5}g(x) [/tex]
Substituting the values of the given limit,
[tex] 23(17)+3(22)=457 [/tex]
