Answer:
hey there where are those numbers
Remember that the angles of a triangle is 180 so:
(7x+8) + (5x+2) + (7x-1) = 180
7x+8+5x+2+7x-1=180
7x+5x+7x=180-8-2+1
19x=171
X= 171/19
X=9
Therefore x=9
36-5 would equal 31 ...........

Answer:
289/4
Step-by-step explanation:
x² + 17x + 12 = 0
x² + 17x = -12
Take half of the second coefficient, square it, then add the result to both sides.
(17/2)² = 289/4
x² + 17x + 289/4 = -12 + 289/4
(x + 17/2)² = 241/4
