X=75
y=75
z=105
as you do 42 + 63=105
Answer:
$424
Step-by-step explanation:
Find area of all surfaces to be covered
20 x 30 = 600 ceiling
10 x 20 = 200 x 2 = 400 two walls
10 x 30 = 300 x = 600 other two walls
Assume no doors
total area is 1600 square feet
multiply by 2 because you are doing two coats
3200 total area to be covered
3200/400 = 8 gallons of paint x $53 = $424
Answer:
Even
Step-by-step explanation:
Well if you have an odd number like 3, 5, 7, 9, and etc multiplied by an even number like 2, 4, 6, 8, and etc you will always get an even number
2 x 3 = 6 which is even 3+3
5 x 4 = 20 which is even 10+10
7 x 6 = 42 which is even 21+21
this is the full answer for you're Q
please give me good
The expression for the perimeter of the rectangle is 2(11c - 11d)
Perimeter of a rectangle = 2(length + width)
Length = 3c - 9d
Length = 3c - 9d Width = 8c - 2d
The expression for the perimeter can be expressed thus :
2(3c - 9d + 8c - 2d)
Collect like terms :
2(3c + 8c - 9d - 2d)
2(11c - 11d)
Hence, the expression for the perimeter of the rectangle is 2(11c - 11d)
