The answer is X is greater than -2! <3
By the external angle theorem
5x = (5x - 30) + m < RST
m < RST = 5x - 5x + 30 = 30
also m < STR = m < SRT = 5x - 30
So as there are 180 degrees in a triangle:-
5x - 30 + 5x - 30 + 30 = 180
10x = 180 +30+30-30 = 210
x = 21 answer

Answer:the answer this is negative 3
Step-by-step explanation:
Area is height time width, or in this case, 3(2x^2+3x+5), which is 6x^2+9x+15.
