Answer:
I do not know
Step-by-step explanation:

17 cm a minute would be 0.01 miles per hour.
We know that for every 5 red bricks there were 2 gray bricks.
The total amount of red bricks and grey bricks in this sample is 7.
5 red bricks + 2 grey bricks = 7 bricks
Now, we divide 175 "total number of bricks used" by 7 "5 red bricks + 2 grey bricks = 7 bricks" and we will get a quotient of 25.
Now we know that 25 bricks is 
of the wall. The gray bricks are 
so we can multiply 25 by 2 and we will get a product of 50. If 1/7 = 25 grey bricks so 2/7 would be the grey bricks.
175 - 50 = number of red bricks.
Therefore, there were 125 red bricks.
<h3>
It is equivalent to 2a+2b</h3>
We use the distributive property.
Multiply the outer term 2 by each term inside ('a' and b)
2 times a = 2a
2 times b = 2b
We add those results to get 2a+2b. We cannot combine these terms as they are not like terms.
Answer:
708meters
Step-by-step explanation:
Given data
Lenght = 274meters
Width= 80 meters
The expression for the perimeter is
P= 2L+2W
substitute
P= 2*274+ 2*80
P= 548+160
P= 708 meters
Hence the perimeter of the block is 708meters
