The triangles shown have the same perimeter. What is the value of x? x + 3
x + 3
X +3
2X-3
x + 3
х

x = 9

Step-by-step explanation:

The perimeter of the first triangle is x + 3 + x + 3 + x + 3 = 3x + 9 and the perimeter of the second triangle is x + 3 + 2x - 3 + x = 4x. We know that the perimeters are equal, therefore, we can write the following equation:

3x + 9 = 4x

x = 9

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

a)(x-2)^2+(y-1)^2=9
