BA=5 AC=3 What is the length of side BD? If needed, write your answer as a simplified fraction using the form a/b. units

4

Step-by-step explanation:

a²+b²=c²

|BD|²+|AC|²=|AB|²

|BD|²+3²=5²

|BD|²+9=25

|BD|²=25-9

|BD|²=16

then you root both sides

therefore |BD|=4

no because mercury has a density of 13.6 grams per centimeter squared while gold has 19.32 grams centimeter squared

step-by-step explanation:

system of linear equation

step-by-step explanation:

as given in the data

a= 20 , b= -12

let us suppose that it is a straight line equation

now we know the formula for the system of linear equation

b= ma + c )

here m is slope of a straight line which is equal to formula

m=   (ii)

and here c is a constant

now putting the value of a and b in equation (ii)

m=

m=

putting the value of a,b and m in equation (i) gives us

-12 = + c

-12=-12 + c

adding 12 to both sides

-12 +12 = -12 +12 +c

0 =c

or c=0

as the value of the constant is zero which gives us that it is a linear equation and this order pair satisfies the system of linear equations.
