The answer would be the <u><em>ASA Postulate</em></u> because of the fact that the two opposite angles are congruent and the line crossing the rectangle is congruent to itself (reflexive Property)
The answer is 9/23 you simply both sides of the equation, subtract 7x from both sides, divide both sides by -23
Is this the full question that is stated?
Step-by-step explanation:
the second equation should be multiplied by 9
Step-by-step explanation:
Given
x² - 9x + 20 = 0
x² - ( 4 + 5) x + 20 = 0
x² - 4x - 5x + 20 = 0
x ( x - 4 ) - 5 (x - 4 ) = 0
(x - 4 ) ( x - 5 ) = 0
Either
x - 4 =0
x = 4
or
x - 5 =0
x = 5
x = 4 and 5
Hope it will help :)
