Solve the equation.
3+ 4.5(2d – 3) = 7.5

d=2

Step-by-step explanation:

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

3+4.5(2d−3)=7.5

Step 1: Simplify both sides of the equation.

3+4.5(2d−3)=7.5

3+(4.5)(2d)+(4.5)(−3)=7.5(Distribute)

3+9d+−13.5=7.5

(9d)+(3+−13.5)=7.5(Combine Like Terms)

9d+−10.5=7.5

9d−10.5=7.5

Step 2: Add 10.5 to both sides.

9d−10.5+10.5=7.5+10.5

9d=18

Step 3: Divide both sides by 9.

9d

9

d=2

d=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

i dont know if you cant find a way its best to actually add all of them start from 105 tho
