Answer:
55
Step-by-step explanation:
let's plug that in to the equation
-6*5+8+5*4-3
=-30+8+20-3
=58-3
=55
If the perpendicular from chord is x, the length of cord is 11.3 and diameter be 15.5 then the value of x is 4.54.
Given Perpendicular from center to chord is x. The length of cord be 11.3 and the diameter be 15.5.
Perpendicular means a line on other line making an angle of 90 degrees. Cord is the length of line joining two points on a circle and is different from radius or diameter. We know that the formula of calculating the length of chord is as under:
l=
now put the value of l=11.3 and r=15.5/2=7.25
11.3=
11.3/2=
5.65=
squaring both sides
31.9225=52.5625-
31.9225-52.5625=-
-20.64=-
20.64=
x=4.54
Hence if the length of cord is 11.3 and diameter is 15.5 then the value of x is 4.54.

Divide by 3 and you get m^2-81 so then factor and get 3(m+9)(m-9)
