To answer this, you will want to find the perimeter in terms of x first. To do this, you just add all the lengths of the sides together: x + (x + 1) + (x + 8) + (x + 5) + (x + 4) + (x + 6) = 6x + 24 = 150.

Solve for x, and you get that x = 21. The longest side is obviously x + 8, so you do 21 + 8 = 29 cm.

Solve for n. F-7 (n-46)

RSB [31]

Answer:

F/7 +46=n

Step-by-step explanation:

(WARNING IDK IF THIS IS THE CORRECT WAY TO SOLVE) Start with the equation itself F-7(n-46). You’re first step is to simplify the equation by distributing -7 to (n-46). So multiple n by -7 and multiply -46 by -7. After that you’re equation should look like f-7n+322. This is when you can start trying to solve for n. You want n on the other side of the equal sign so you’re going to add -7n to the one side of the equal sign. F+322=7n. Now to get n by itself divide 7 to both sides of the equation. This will give you F/7+6=n.
