Consider the triangle below.
Find the perimeter of triangle ABC. Round to the nearest hundredth.

A) 18.86 units
B) 120 units
C) 13.47 units
D) 6.43 units

Option A is correct.

Step-by-step explanation:

Using the above mentioned distance formula, we have:

Add the length of three sides of triangles, we have:

Perimeter = 5.39+6.4+7.07 = 18.86

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct

the solution is x=1

step-by-step explanation:

we are given our   equation as

let's assume

left side function is

right side function is

now, we can draw graph

and then we can get intersection point

the intersection point will be solution

so, the solution is

x=1
