x est approximativement égal à 0.906 et -1.656
Step-by-step explanation:
x + (2x + 3) + 4x² - 9 = 0
4x² + x + 2x + 3 - 9 = 0
4x² + 3x - 6 = 0
Nous ne pouvons pas prendre en compte cela, nous allons donc passer par la résolution de x à la place.
Commençons par compléter le carré:
4x² + 3x = 6
4x² + 3x + 9 / 16 = 6 + 9 / 16
(2x + 3/4)² = 96 / 16 + 9 / 16
(2x + 3/4)² = 105 / 16
2x + 3/4 = ± √105 / 4
2x = -3/4 ± √105 / 4
2x = (-3 ± √105) / 4
x = (-3 ± √105) / 8
x ≈ 0.906, -1.656
Answer:
16
Step-by-step explanation:
do the parenthesis first, you get 11 2/3 from that. Then do 4 1/3 + 11 2/3, you get 16
Answer:
The rug is two feet too wide
Step-by-step explanation:
Well first, let's figure out the diameter of the rug to see if it will fit in the room. We know that the circumference of the circle is πd. So we can solve for d from there (d is the diameter).
c = πd
50.24 = πd
50.24/π = d
d = about 16 ft
Knowing this, we know that the rug would not fit in the room and if it was centered, it would have a foot of rug sticking out from each wall. Therefore, the rug is two feet too wide.
Answer:
m=1
Step-by-step explanation:
calculate slope (m) with this formula: (y2-y1)/(x2-x1)
here are the given points: (0,0) and (3,3)
label the points
x1=0
y1=0
x2=3
y2=3
now substitute into the equation
m=(3-0)/(3-0)
m=3/3
m=1
the slope is therefore 1
hope this helps :)
