Answer:6.5
Step-by-step explanation: If you simplify (3 x 2) into 6, it will leave 6+6x=45. So if you subtract 6 on both sides it will cancel out the one on the left and make 45 into 39. So now you have 6x=39 so now you just divide 6 on both sides and get 6.5.
The two quadrilaterals are given similar .
In any similar figure sides are in proportion.The second largest side of quadrilateral ABCD is 16 ft .Let the second longest side of quadrilateral EFGH be x ft. These sides will be in proportion to each other .
The second shortest side of quadrilateral EFGH that is GF will be proportional to the third longest side of quadrilateral ABCD that is BC
We can form a proportion with the proportional sides:
To solve for x we cross multiply
12x=(16)(18)
12x=288
Dividing both sides by 12 we get
x=24.
The second longest side of quadrilateral EFGH is 24 ft.
Someone who shows respect
You divide the top by the bottom. 8/18=.44
The answer to the question is (x+14)•(x+14)
