Answer:
x² - 6x + 9 = 0
Step-by-step explanation:
Given
(x - 3)² = 0 ( expand left side using FOIL )
x² - 3x - 3x + 9 = 0 ( collect like terms )
x² - 6x + 9 = 0 ← in general form
9514 1404 393
Answer:
25/416
Step-by-step explanation:
Maybe you want to know the value of ...
(1 1/4)/(20 4/5) = (5/4)/(104/5) = (5/4)×(5/104) = (5×5)/(4×104) = 25/416
30-5*4+2
30-20+2
10+2
12 is the answer
Answer:
Step-by-step explanation:
The sum of the angles of a triangle is always 180°.
(2x+4) + (2x-2) + (x-2) = 180
5x = 180
x = 36°
Answer:
567 mph
Step-by-step explanation:
The speed will actually just be the slope of the line. Slope is change in y-coordinates over change in x-coordinates. We can pick any two points for this; let's just do (1, 567) and (2, 1134).
Slope = (1134 - 567) / (2 - 1) = 567 / 1 = 567
The speed is thus 567 miles/hour.
