Write an expression for the perimeter of the triangle shown below: a triangle is shown with side lengths labeled 0.5x plus 9, 3x, and negative 3.4x minus 25.

0.1x - 16

Hope this helps!! :)

38+105= 143, 39+104=143, and you will find then adding the numbers on opposite sides, moving inwards yields the answer 138 every time. because of this, you’re going to multiply 138 times the number of pairs, which is 34. therefore, 34*138= 4692(i’m sorry if it’s the wrong numbers, but it’s the right concept)

0.69 yards

step-by-step explanation:

there are 36 inches in a yard

25 : 36 = 0.69 yards (you can round to 0.70)
