Triangle with sides of 8.2cm,3.9cm, and 4.5cm. what is the perimeter?

Perimeter is the measurement all around the shape. So, to do this we wolud need to add this measurments together

Step-by-step explanation:

8.2+3.9=12.1

12.1+4.5=16.6

16.6cm

pls let me know if it was correct

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.
