Answer:
5/14
Step-by-step explanation:
let the aaded no be x
3/14 + x = 4/7
x = 4/7-(3/14)
x = 5/14
here added no is 5/14
The plot of land forms right triangle.
Step-by-step explanation:
Let,
the three sides are a,b and c.
The sum of square of two sides equals to the square of third side. We will consider the larger side as c, therefore,
a= 2000 feet
b= 2100 feet
c= 2900 feet
Using Pythagoras theorem;

As the three sides satisfy pythagoras theorem, therefore, the plot of land form right triangle.
The plot of land forms right triangle.

Answer:
(3a³-5b³)+ (-2)a³ +6b³=(a³+b³)
Step-by-step explanation:
First, lets remove the brackets. There is no "-" before the brackets, so we can just remove them at all.
3a³-5b³+ ...a³ +...b³=a³+b³
Now we can joint similar monoms (with variable a) ( and with variable b) in the left side of equation
3a³+...a³ -5b³ +...b³=a³+b³
Now we can notice that 3a³+...a³=a³ (1) and
-5b³ +...b³=b³ (2)
Lets find deduct 3a³ from both sides of (1)
...a³= a³-3a³
...a³= -2a³ So instead ... we have to type -2 (-2 is negative sowe type -2 in brackets).
Similarly lets add 5b³ to both sides of (2)
-5b³ +...b³=b³
-5b³ +5b³ +...b³=b³+5b³
...b³=6b³ So instead ... we have to type 6.
Y = - x^2 - 2
the vertex of - x^2 will be at (0,0)
the -2 translates the graph down 2 units
The answer is the vertex is at (0,-2) and as the coefficient of x^2 is negative it is a maximum
Answer is D.
