NO ONE IS HELPING ME PLEASE IM FINNA CRY I SWEAR I BEGGING YOU

What is the square root of 45? (step by step working plz)

Solve for x and y: 217x + 131y = 913; 131x + 217y = 827

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.
