Question

Write an equation to show the height of the two buildings are equal to each other. Then solve for x. Show all your steps when solving.

. X=18
. X=308
. X=92
. X=108
. X=28

Answer 1

X = 108.

Explanation:

Heights are equal, So equation will be,

`4 + 3 √(x - 8) = 34`

So, solving the eq.

Subtract 4 from both sides ,

`3 √(x - 8) = 30`

Divide 3 to both sides,

`√(x - 8) = 10`

Squaring both sides,

`x - 8 = 100`

Add 8 to both sides,

`x = 108`
