x² - 14x + 46 = 0
subtract 46 from both-side
x² - 14x = -46
Add the square of the half of the co-efficient of x
x² - 14x + (-7)² = -46 + 7²
(x-7)² = -46 + 49
(x-7)² =3
Take the square root of both-side
x-7 = ±√3
x-7= ±1.732
Add 7 to both-side of the equation.
x= 7 ± 1.732
Eithe x= 7 + 1.732 or x= 7 - 1.732
x=8.732 or x=5.268
Therefore x = 8.732 , 5.268
Answer:
No,
12.8 = 12.800
Obviously, 12.800 <u>< </u>12.815.
Answer:
there are 9 cubes
make me brainliest if u r satisfied
Answer:
v = 9
Step-by-step explanation:
Since the triangles are similar then corresponding angles are congruent
∠B and ∠Q are corresponding angles, hence
6v - 5 = 5v + 4 ( subtract 5v from both sides )
v - 5 = 4 ( add 5 to both sides )
v = 9
