Atriangle has one side that measures x, another side that measures 2x, and a third side that measures 5 less than x. the perimeter is 31 inches. which equation would you use to find the value of x? explain your answer a. x + 2x + x - 5 = 31 b. x + 2x + x + 5 = 31 c. x + 2x - x - 5 = 31 d. x + 2x - x + 5 = 31

Iwill give ! if m∠a=59 and m∠3=81°, what is m∠b? m∠b= _[blank]_°

Can some one me with these questions

20 points 1. your friend, taylor, missed class today and needs some identifying solutions to systems. explain to taylor how to find the solution(s) of any system using its graph. 2. taylor graphs the system below on her graphing calculator and decides that f(x)=g(x) at x=0, x=1, and x=3. provide taylor some feedback that explains which part of her answer is incorrect and why it is incorrect. f(x)=2x+1 g(x)=2x^2+1
