slant height(h) = 16.3ft

Base side = 20ft

\text{Area of pyramid=}\frac{1}{2\text{ }}\times perimeterofbase\text{ x slant height}

Perimeter of base = 4(base side) = 4(20) = 80ft

\begin{gathered} \text{Area of pyramid = }\frac{1}{2}\times80\times16.3 \\ \text{Area = }652ft^2 \end{gathered}

elixir [45]

Answer:

y= -x

Step-by-step explanation:

<u>slope- intercept form</u>

y= mx +c, where m is the slope and c is the y-intercept.

Given that the slope is -1, m= -1.

Substitute m= -1 into the equation:

y= -x +c

To find the value of c, substitute a pair of coordinates into the equation.

When x= 2, y= -2,

-2= -2 +c

c= -2 +2

c= 0

Thus, the equation of the line is y= -x.

Solve the system by the elimination method.
PolarNik [594]

Answer:

6x = 12

Step-by-step explanation:

2x + 3y - 10 = 0

4x - 3y - 2 = 0

add the two equations

2x + 3y - 10 = 0

4x - 3y - 2 = 0

--------------------

6x -12 = 0

add 12 to each side

6x -12 +12 = 0+12

6x =12

divide by 6

6x/6 =12/6

x =2
