Ill give brainiest, dont guess please

Me ! write an equation for the interior angles of this triangle that uses the triangle sum theorem

Given the equation f(x)=a(b)x where the initial value is 40 and the growth rate is 20% what is f(4)

With this question substitute t=3 and t=5 to determine if the two expressions are equivalent. 4(t + 3) 4t+12 which statements are true? check all that apply. a. the value of both expressions when t =5 is 32. b. the two expressions are not equivalent. c. the value of both expressions when t=3 is 15. d. the value of both expressions when t=5 is 23. e. the two expressions are equivalent. f. the value of both expressions when t=3 is 24.
