Answer:

28/3

Step-by-step explanation:

We see that the triangles are simalar to eachother, so we can set up this ratio:

x/(8+x) = 7/13

x = 56/13 + 7x/13

13x = 56 + 7x

6x = 56

x=56/6=28/3

NeX [460]

Step-by-step explanation:

  • a=13
  • d=13-9=4

{:}\longrightarrow\sf S_n={\dfrac {n}{2}}\left [2a-(a-1)d\right]

{:}\longrightarrow\sf S_101={\dfrac {101}{2}}\left [26 (12)4\right]

{:}\longrightarrow\sf 50.5×1248

{:}\longrightarrow\sf S_101=63504

  • {:}\longrightarrow\sf a_n=a+(n-1)d

{:}\longrightarrow\sf a_101=13+(101-1)-4

{:}\longrightarrow\sf a_101=13+100(-4)

{:}\longrightarrow\sf 13-400

{:}\longrightarrow\sf a_101=-387
