Yes, sqrt of 1815, cannot be rationalized
Could be 40 degrees something llike that. looks like a 40 degree
Answer:
No
Step-by-step explanation:
(-5 + x)( x + 4)= -5*(x+4) +x*(x +4 )
= -5x -20 +x² + 4x
= -5x + 4x + x² -20 = -x + x² -20
= x² - x - 20
(5 + x) (x -4) = 5*(x-4) + x (x-4)
= 5x - 20 + x² - 4x
= 5x - 4x +x² -20 = x + x² - 20
= x² + x - 20
that picture dont make sense you need a better one sorry
