What is the lateral area of this regular octagonal pyramid?
the figure shows a regular octagonal pyramid. a dashed line segment is shown perpendicular to a base edge with its second endpoint being the center of the base and has a length of 8 centimeters. a second dashed line segment has one endpoint at the center of the base and the second endpoint at the vertex of the pyramid and has a length of 8 centimeters. a base edge has a length of 6.6 centimeters.
a) 149.3 cm²
b) 182.9 cm²
c) 211.2 cm²
d) 298.7 cm²

298.7

Step-by-step explanation:

I just took the test

step-by-step explanation:

in the absence of parentheses, i will have to make some assumptions:   i interpret your (3x+5/y^6)(4y^3/5)​ to mean:

3x + 5     4y^(3/5)       (3x + 5)(4)

* =

    y^6             1               y^(6-3/5)

if this is not what you expected, repost your question using parentheses to indicate whether you meant

4y^3

    or   4y^(3/5)

    5

arrange the equations with like terms in columns.

analyze the coefficients of x or y.

add the equations and solve for the remaining variable.

substitute the value into either equation and solve.

check the solution.
