Need help with question 4 and question 5 please!

The areas of two similar triangles are 72dm2 and 50dm2. the sum of their perimeters is 226dm. what is the perimeter of each of these triangles?

Side xy of triangle xyz is extended to point w, creating a linear pair with ∠wyz and ∠xyz. measure of an exterior angle what is the value of x? 64 80 100 180

A.)complete this table by reading the values from the graph. estimate any function values that are less than one. x -3 -2 -1 0 1 2 3 exponential function linear function b.)at approximately what values of x do both the linear and exponential functions have the same value for y?
