Answer:
1.
C. 5y -7 is an algebraic expression difference with two terms.
Please do not mind me I am just trying to answer questions so I can message
<span>The incenter is equidistant from all three triangle sides.
So, PJ = PK = PL.
PJ = 4x -8
PL = x + 7
Therefore,
</span>4x -8 = <span>x + 7
3x = 15
x = 5
So, PJ = 12
PL = 12 and
PK = 12
</span>
The answer would be 7776^2 / 343^2 written as a fraction OR about 513.95402 written as a decimal.
