Here it is: 0.156
That is the decimal representation of 156/1000
Answer:
{-15, -5}
Step-by-step explanation:
The constant on the left needs to be the square of half the x-coefficient:
(20/2)^2 = 100
To get it to that value, we can add 18 to both sides of the equation:
x^2 +20x +100 = 25 . . . add 18 to both sides of the equation
(x +10)^2 = 25 . . . . . . . . write the left side as a square
x +10 = ±√25 = ±5 . . . . . take the square root
x = -10 ±5 = {-15, -5}
The solutions are x = -15 and x = -5.
_____
The attached graph shows the solutions to ...
x^2 +20x +82 -7 = 0 . . . . . the result of subtracting 7 from both sides
Answer:
AD ≅ CD.
Step-by-step explanation:
Statement : consider triangles ADB and DBC.
1) AB = CD
2) ∠ABD = ∠DBC
3) DB = DB
4) ⇒ ΔADB and ΔDBC are congruent triangles.
5) AD = DC.
Reasons ;
1) given, AB = CB
2) given, DB bisects ∠ ABC
3) common side of both triangles
4) as two sides and one angle are equal in both triangles
5) congruent triangles
Answer:
they are alternate interior angles and because we have parallel lines these two angles are equal
these angles are equal to 115°
Step-by-step explanation:
57x+1=56x+3
57x-56x=3-1
x=2
57x+1=57*2+1=114+1=115°
56x+3=56*2+3=112+3=115°
