PLEASE HELP‼️‼️‼️ A BiG PERCENTAGE OF MY GRADE: Find the perimeter as a polynomial/ show work

26x +5

Step-by-step explanation:

To find a perimeter, you need to add the length of all lines. In this picture, we don't know the length of the vertical line on the left and horizontal line on the bottom yet.  

The vertical line on the left should be equal to the sum of two vertical lines on the right, 3x and 3x. The length will be: 3x + 3x = 6x

The horizontal line on the bottom should be equal to the sum of two horizontal lines on top, 3x and (4x+5). The length will be: 3x + 4x +5= 7x +5

The perimeter will be: 3x + 3x + 4x+5 + 3x + 7x+5 +6x= 26x +5

d. bc = 12 and ef = 16

step-by-step explanation:

we are given that δabc : δdef such that .

also, it is given that

so, from the options, we need that .

a.

b.

c.  

d.

as, we can see that only option d gives the same ratio as i.e. .

hence, the possible lengths are bc = 12 and ef = 16.
