The perimeter of the triangle is 15.7 inches, so the equation to solve is 2a + b = 15.7. which lengths make sense for possible values of b?

Sorry guys but as you have a small brain

The parabola y = x² - 4 opens: a.) up b.) down c.) right d.) left

Asap describe the transformations required to obtain the graph of the function f(x) from the graph of the function g(x). f(x)=-5.8sin x. g(x)=sin x. a: vertical stretch by a factor of 5.8, reflection across y-axis. b: vertical stretch by a factor of 5.8,reflection across x-axis. c: horizontal stretch by a factor of 5.8, reflection across x-axis. d: horizontal stretch by a factor of 5.8 reflection across y-axis.
