Answer:
56 
Step-by-step explanation:
Volume of bigger rectangular prism is 4*3*4 (48).
Volume of smaller rectangular prism is 1*2*4 (8).
48 + 8 = 56.
Answer:
A) 4*4x-4*3 and 16x-12
B) 12y+15y and 27y
Step-by-step explanation:
For A when you do the distributive property, you get:
4(4x-3)
4*4x-4*3 (which is one of the choices)
16x-12 (which is one of the choices)
For B when you combine like terms, you get:
12y+5y+10y
12y+15y (which is one of the choices)
27y (which is one of the choices)
25 000,000/10,000
Cross out equal amounts of 0's from both numbers:
There are 4 0's in 10,000, so remove 4 0's from both numbers to get:
2500/1
Any number over 1 is that number:
2500/1 = 2500
It's the same because it's used the commutative property where:
a+b = b+a
So, 86+68+38=192 it's the same sum as 68+38+86=192
Answer:
9 rolls
Step-by-step explanation:
The perimeter of the room measures 2(19' +12') = 62', so the area of the walls is ...
(62 ft)(8.5 ft) = 527 ft²
We know that 8 rolls will cover 8×60 ft² = 480 ft², and 9 rolls will cover 540 ft², so we will need 9 rolls to cover the walls.
