Answer:
A. √16
Step-by-step explanation:
A perfect square is any number that can be expressed as a product of an integer and itself. i.e. 4 can be represented as 2 × 2. Therefore, 4 is a perfect square.
From the options given, the only radical expression that has two perfect square is √16.
√16 consists of two perfect squares, which are 4 and 4.
4 can be expressed as 2 × 2.
Thus: √16 = √(2 × 2)(2 × 2).
Therefore, √16 consists of two perfect squares.
Answer: Inconsistent.
Step-by-step explanation:
The equation of the line in Slope-intercept form is:

Where m is the slope and b is the y-intercept.
Solve for y from each equation:
Equation 1:

Equation 2:

A system of equations can be classified by its number of solutions.
You can observe that the slopes of both equations are the same but the y-intercepts are different, then these lines are parallel, which means that they do not intersect.
By definition, when to lines are parallel there is NO SOLUTION and the system is classified as "Inconsistent".
Answer:
8+1
Step-by-step explanation:
(12/4) * 3
Answer:
Approximately 439.6 square millimeters.
Step-by-step explanation:
The formula for the surface area of a cone is the following:

Where, <em>r </em>is the radius and <em>l</em> is the slant height.
The radius is 7 and the slant height is 13. We also use 3.14 for π Thus:
