Answer:
16.19
Step-by-step explanation:
Use the cosine rule:
Answer:
The zeros are x=4, -2
Step-by-step explanation:
Its zeros can be found by setting the function to zero. The values of x that represent the set equation are the zeroes of the function. To find the zeros of a function, find the values of x where f(x) = 0.

Answer:
-3 + sqrt 42
-3 - sqrt42
Step-by-step explanation:
assuming you want me to factor it and then find the roots:
2x^2 +12x-66
2(x^2 + 6x-33)
It is possible. You can have the same angle measurements and different side lengths. Making it a different triangle.
The area of the pond is
Area = l * w
Area = 50 * 50
Area = 2500 square meters.
Then there is a sidewalk with 5 meters wide around the pond.
So the new dimension is
60 * 60
Area = 60 * 60
Area = 3600
Then at 45 m^2 = $74
= 3600 / 45 * 74
= $5,920
So the total cost of tile is $5,920.
