The statement at the top says that the triangles are 'similar'. That means that the corresponding angles are equal, and each pair of corresponding sides have the same ratio. From the 4 and the 8, you can see that each side in the small one is 1/2 the length of the corresponding side in the big one. So the missing sides are 1/2 the length of the 7 and the 12.
HI :)
First we must distribute the 2.6 to everything inside the ()
The new equation would then be
14.3p-32.24 = 127.92
Then you would add a -32.24 to each side of the equal sign, so that the 32.34 would become a zero pair on the right side of the equal sign and cancel.
The new equation would then be
14.3p = 160.16
Then you divide each side of the = by 14.3, that way the p becomes isolated.
14.3p/14.3 = 160.16/14.3
Then you're left with
p = 11.2
Hope this helped :)
