Hey, what do you need help with ?
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.
Answer:
3a – 4b + 6c – 3d
when a = 5 b = 4 c = 3 d = 2
the value
= 3×5 - 4×4 + 6×3 - 3×2
=15-16+18-6
=11
Hope this helps! the answer is option (A). if you still don’t understand after looking at my solution feel free to clarify ya
The LCM will be the values that are common to both factors. From the given values the LCM will be 2² * 3² * 5
<h3>Least common multiple</h3>
LCM is the lowest number that can divide all other numbers given in an expression.
Given the prime factorizations 2² * 3² * 5 and 2*3*5. The LCM will be the values that are common to both factors.
From the given values the LCM will be 2² * 3² * 5
