Answer:
3( n + 
)² - 
= 0
Step-by-step explanation:
3n² = 6 - 17n ⇔ 3n² + 17n - 6 = 0
3( n² + 2 × n + ( )² - ( )² - 2 ) = 0
3( n + )² - 3 × 
- 6 = 0
3( n + )² - = 0
In centre is the centre of a circle that is inscribed in a triangle, called the incircle, i.e. circle is tangent to all three sides AND located inside the triangle. An incircle is roughly sketched in the accompanying diagram.
Since all radii of an incircle are equal, we have
4x-1=6x-5
Solving for x,
6x-4x=5-1
x=2
consequently, distance from incentre to each side of the triangle is
4(2)-1=7
check 6x-5=6(2)-5=7... checks.
Answers:
The value of x = 2
The distance from incentre to side of triangle is 7
The <em>correct answer</em> is:
The first number is 0.062.
Explanation:
Let x represent the first number in the list.
We add 0.001 to each number to find the next number; this gives us:
x + 0.001 + 0.001 = 0.064
Combining like terms, we have:
x + 0.002 = 0.064
Subtract 0.002 from each side:
x + 0.002 - 0.002 = 0.064 - 0.002
x = 0.062
Answer:
148
Step-by-step explanation:
a line (cd) is 180°
cba + and must be 180°
180-33=148
