Marcus solved for x in the quadratic equation x2 – 10x + 25 = 0. x = x = x = what is true about marcus’s work? check all that apply. marcus should have substituted –10 for b, not 10. the denominator should be 1, not 2. marcus should have subtracted 4(1)(25) in the square root. this equation, when solved correctly, only has 1 real number solution. this equation has 2 real number solutions.

if im undersanding the question correctly, its organized from 10

step-by-step explanation:

step-by-step explanation:

. your answer will contain x - and y -terms. (1 point) x ( ¿¿ 2 − 7 ) 2 +( y 2 − 9 ) 2 √ ¿ 12. what is the distance from the directrix (the crocodile river) to the point ( x , y )? write this equation. your answer will contain a y -term.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
