Answer:

The lateral surface area of a regular pyramid is the sum of the areas of its lateral faces. The total surface area of a regular pyramid is the sum of the areas of its lateral faces and its base. The general formula for the lateral surface area of a regular pyramid is where p represents the perimeter of the base and l the slant height. Example 1:Find the lateral surface area of a regular pyramid with a triangular base if each edge of the base measures 8 inches and the slant height is 5 inches.The perimeter of the base is the sum of the sides.p = 3(8) = 24 inchesThe general formula for the total surface area of a regular pyramid is where p represents the perimeter of the base, l the slant height and B the area of the base. Example 2:Find the total surface area of a regular pyramid with a square base if each edge of the base measures 16 inches, the slant height of a side is 17 inches and the altitude is 15 inches.The perimeter of the base is 4s since it is a square.p = 4(16) = 64 inches The area of the base is s2.B = 162 = 256 inches2T. S. A. = There is no formula for a surface area of a non-regular pyramid since slant height is not defined. To find the area, find the area of each face and the area of the base and add them.

tankabanditka [31]

Step-by-step explanation:

left side of the expression has an x^2 term, x term and constant(x^0 term), same for the right side of the expression

x^2 coefficient = p(-5) + 4(-3qx) = -5p -12qx

Dmitriy789 [7]

Answer:

The Answer is: a^2 + 2ab + b^2

Step-by-step explanation:

Multiply the first factor resulting in the a squared, then the two inner factors resulting in ab + ab, finally the last term, resulting in b squared. Then combine terms:

(-a - b)(-a - b) =

a^2 + ab + ab + b^2 =

a^2 + 2ab + b^2

Hope this helps! Have an awesome day! :-)
