Step-by-step explanation:
A root with square root or under root is only obtained when we take the square root of both sides. Remember that when we take a square root, there are two possible answers:
- One answer with positive square root
- One answer with negative square root
For example, for the equation:
If we take the square root of both sides, the answers will be:
Only getting one solution with square root is not possible. Solutions with square root always occur in pairs.
For given case, the roots are 6 and . Therefore, the 3rd root of the polynomial function f(x) had to be -
It seems you made error while writing option B, it should be - square root of 5.
Answer:
Surface area of pyramid with base equilateral triangle is square inches
Step-by-step explanation:
Recall the following result:
The total surface area(S) of a regular pyramid is given by,
...... (1)
Here, p represents the perimeter of the base , the slant height and B the base area of the pyramid.
From the given information:
Side of equilateral triangle = 20 inches
Slant height of the pyramid() = 13 inches.
First find the perimeter and Area of the base pyramid.
Perimeter of equilateral triangle(p) =
=
Area of equilateral triangle(B) =
= square inches.
Substitute the above values in equation (1) as shown below:
square inches
Hence, the surface area of pyramid with base equilateral triangle is square inches.
