Solve the equation 5x+2x+4=18

x=

x=2

Step-by-step explanation:

Let's solve your equation step-by-step.

5x+2x+4=18

Step 1: Simplify both sides of the equation.

5x+2x+4=18

(5x+2x)+(4)=18(Combine Like Terms)

7x+4=18

7x+4=18

Step 2: Subtract 4 from both sides.

7x+4−4=18−4

7x=14

Step 3: Divide both sides by 7.

7x /7 = 14/ 7

x=2

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
