What is the area of triangle abc if a = 8, b = 11, and c = 15?

True or false look at the picture pls : /

Given the equation y − 4 = three fourths(x + 8) in point-slope form, identify the equation of the same line in standard form. −three fourthsx + y = 10 3x − 4y = −40 y = three fourthsx + 12 y = three fourthsx + 10
