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
Right on top of 'a'. They'll look like one single point on the number line.
The answer is 250000

Heya!
Here is your answer:
6a²-15a-8a+20
= 3a(2a-5) -4(2a-5)
= (3a-4)(2a-5)
