Given the definitions of f(x) and g(x) below, find the value of (g o f)(1). f(x) = x² + 7x + 1
g(x) = -5x + 8

What does x = in this equation x+3+2x=x+5

What is the value of f(x) = 2.2 for f(-2)?

Look at the figure below: triangle abc is a right triangle with angle abc equal to 90 degrees. the length of ac is 5 units and the length of ab is 4 units. d is a point above c. triangle adc is a right triangle with angle dac equal to 90 degrees and dc parallel to ab. what is the length, in units, of segment cd?
