4y + 24 is the answer to that equation.
We're going to use the equation given but let's first make sure we understand what the equation IS saying:
Area of a kite= [(1st diagonal) × (2nd diagonal)]/2
Now, let's find the 2 diagonals. In the case of kite shapes one of the diagonals is the line that goes from W to Y and the other is the line going from X to Z. In a kite they will always cross (no matter their lengths).
Now that we know the diagonals we can add the lengths that are given for each line to know what to multiply.
Line W to Y: 20+12= 32
Line X to Z: 12+12= 24
Now let's plug these numbers into the equation (it doesn't matter the order of the diagonals because we're just gonna be multiplying them either way!)
So...
(32×24)/2= 384 units squared (because it is area)
Answer:
Dharma and Jorge should purchase a group plan.
They could save $9.55
Step-by-step explanation:
A group plan will cost an average of $135.95 per month.
An individual plan will cost an average of $72.75 per month.
Two individual plans will cost an average of

per month.
Since $145.50 > $135.95, Dharma and Jorge should purchase a group plan.
They could save

SOLUTION
We have been given the equation of the decay as

So we are looking for the time
Plugging the values into the equation, we have

Taking Ln of both sides, we have

Hence the answer is 4308 to the nearest year
