Answer:
=41
Step-by-step explanation:
X = 4 and y =5
6(
) - 
= 6 (16-5) -25
= 6 (11)-25
= 66 -25
=41
X² + x - 20 = 0
x² = x * x
x = the sum of the factors of -20
-20 ⇒ 1 x 20
2 x 10
- 4 x 5 ⇒ only these factors can arrive to a sum of 1
(x - 4)(x + 5) = x(x+5) - 4(x+5) = x² + 5x - 4x - 20 = x² + x - 20
x - 4 = 0
x = 4
x + 5 = 0
x = -5
