Answer:

(a) Area = (\frac{x}{4})^2

Step-by-step explanation:

The question is incomplete. (See comment for complete question).

From the completed question, we have:

Total\ base\ length = x

n = 8 --- number of pyramids

Required

An expression for the area of the base

The total base length of the pyramid represents the perimeter of the base.

And since the base is a square, then the following relationship exist.

Total\ base\ length = 4L

Where L represents the length of each side.

This gives

4L = x

Make L the subject

L = \frac{x}{4}

The area of the base is then calculated as:

Area = L^2

Area = (\frac{x}{4})^2

If all perpendicular lines are also intersecting lines, are all interesting lines also perpendicular lines? Explain, you'r answe
DerKrebs [107]

No.

Perpendicular lines are lines that intersect at a 90° angle.

If two lines are perpendicular, they create four 90° angles.

However, for two lines to intersect, they do not necessarily have to intersect at a 90° angle.

Use the quadratic formula to determine the exact solutions to the equation.
kozerog [31]
Answer:  " x = 1  + √5 " or " x = 1 − √5" .
______________________________________________________
Given:
______________________________________________________

   " x² − 2x − <span>4 = 0 " ;
______________________________________________

Solve for "x" by using the "quadratic formula" :

</span>Note:  This equation is already written in "quadratic format" ; that is:

  " ax² + bx + c = 0 " ;  { "a \neq 0" } ;

in which:   "a = 1" {the implied coefficient of "1" ;
                         since "1", multiplied by any value, equals that same value};

                 "b = -2 " ;

                 "c = -4 " ;
_______________________________________________________
The quadratic equation formula:

x = { - b ± √(b² − 4 ac) } / 2a ;   {"a\neq0"} ;
______________________________________________________
Substitute our known values:
______________________________________________________

   →  x = { - (-2) ± √[(-2)² − 4(1)(-4)] } / 2(1) ; 

       →  x  = { 2 ± √(4 − 4(-4) } / 2 ; 

       →  x  = { 2 ± √(4 − (-16) } / 2 ;

       →  x  = { 2 ± √(4 + 16) } / 2 ;

       →  x  = { 2 ± √(20) } / 2 ;

       →  x  = { 2 ± √4 √5} / 2 ;

       →  x  = { 2 ± 2√5} / 2 ;

       →  x = 1 ± √5 ; 

_______________________________________________________
→  "x = 1 + √5"  or  "x = 1 − √5" .

Evaluate the equation
gregori [183]

Answer:

3 +4 i

Step-by-step explanation:

x + sqrt(yz)

Let x = 3 y=2  and z = -8

3 + sqrt(2*-8)

3+ sqrt(-16)

3 + sqrt(16) sqrt(-1)

We know sqrt(-1) = i

3 +4 i
