Answer:
$532 for both rooms.
208 for dining room. 324 for living room.
Step-by-step explanation:
Find out how much square foot is in both rooms by multiplying length and width. then multiply each rooms square foot .by 2. then add up the two.
Combining like terms:
First do the first part which is 6(u-4)-8, you first distribute 6 to u and -4, 6u-24-8
-24-8=-32, 6u-32
Second part the same thing , distribute -6 to -4u and 6, (negative times a negative equals a positive) 24u-36-2u
24u-2u=22u
Solving:
6u-32=22u-36
Subtract 6u on both sides, -32=16u-36
Add 36 on both sides, 4=16u
Divide 16 on both sides
U=4/16 which is 0.25
It would just be 8 since an integer just means whole number.
