The sum of three consecutive even integers is- 78. what are the integer? describe how you would use the strategy of writing an equation solve the given problems

Let x = the smallest even integer, x + 2 = the next even integer, and x + 4 = the largest even integer.

Write the equation x + x + 2 + x + 4 = –78.

Simplify the equation as 3x + 6 = –78.

Solve the equation by subtracting 6 and dividing by 3 on both sides of the equation.

Check that the sum of the integers –28,

–26, and –24 is –78.

Step-by-step explanation:

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
