<h3>4.4 quarts of paint needed to cover the walls of a room with a perimeter of 55 feet and 8-foot walls</h3>
<em><u>Solution:</u></em>
Given that,
The amount of paint needed to cover the walls of a room varies jointly as the perimeter of the room and the height of the wall
<em><u>The formula for joint variation is:
</u></em>

Where,
z is the amount of paint needed
x is the perimter of room
y is the height of room
<em><u>Room with a perimeter of 35 feet and 10 foot high walls requires 3.5 quarts of paint</u></em>
Therefore,

<em><u>find the amount of paint needed to cover the walls of a room with a perimeter of 55 feet and 8-foot walls</u></em>
Substitute k = 0.01, x = 55 and y = 8 in joint variation formula

Thus, 4.4 quarts of paint needed to cover the walls of a room with a perimeter of 55 feet and 8-foot walls

Answer:
d=7
Step-by-step explanation:
An=A1+(n-1)d
32=11+(4-1)d
32=11+3d
-11+32=3d
21=3d
d=7
