Sos i need i'm not good at math just reading and !

Given the two similar triangles, how do i find the missing length? if a=4, b=5, and b'=7.5 find a'

Select the point that is a solution to the system of inequalities. y< =-x+3 y=x^(2)-3x

The equation represents the function f, and the graph represents the function g. f(x)=3(5/2)^x determine the relationship between the growth factors of f and g. a. the growth factor of g is twice the growth factor of f. b. the growth factor of f is twice the growth factor of g. c. the growth factor of f is 2.5 times the growth factor of g. d. the growth factor of f is the same as the growth factor of g.
