The value of x will be2.217 and PR will be 13.085 units.
<h3>What is a line segment?</h3>
A line section that can connect two places is referred to as a segment.
In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.
The line is here! It extends endlessly in both directions and has no beginning or conclusion.
Given that,
Line PQ consists of two segments PR and RQ
So,
PQ = PR + RQ
17 = 5x+2 + x² - 1
x² + 5x - 16 = 0
The roots of the equation will be
x = [-5 + √(25 + 64) ] ÷ 2
x = 2.217
Now,
PR = 5(2.217) + 2 = 13.085
Hence "The value of x will be2.217 and PR will be 13.085 units".

A 120 watt light-bulb is a 0.120 kilowatt light bulb.
In one hour, it uses 0.120 kilowatt-hour of energy.
If electrical energy costs $0.20 per kilowatt hour, then that light bulb costs
(0.120 kilowatt-hour / hour) x (0.20 dollar / kilowatt-hour) =
(0.120 x $0.20 / hour) =
$0.024 / hour = <span>2.4¢ per hour </span>
So
lets say we have
a/b=2a/2b
we know that if we invert one and multiply it by the other (divide them), we get 1 because a/a=1 where a=a
so
2/3 and 4/6 are equivelent because if you divide them we get 12/12=1
2/3 and 8/12 are equivilent because if you divide them we get 24/24=1
and sinde 2/3=4/6 and 2/3=8/12, 2/3=4/6=8/12
they are equivlent
The answer is (2,1). 2*2=4 and 9*1=9. 9+4=13
