Answer:
Length of one side of the region containing small squares is 16 inches.
Step-by-step explanation:
Given:
Area of the chess board = 324 square inches
Border around 64 -squares on board = 1 inch
We need to find the length containing small squares.
Solution:
Let the length of one side of the chess board be 'L'.
Now we know that;
Border around 64 -squares on board = 1 inch
So we can say that;
Length of the side of the chess board = 
Now we know that;
Area of square is equal to square of its side.
framing in equation form we get;
Now taking square root on both side we get;
Now subtracting both side by 2 we get;
Hence Length of one side of the region containing small squares is 16 inches.
Answer:
11 meters is her approximate reaction distance.
Step-by-step explanation:
Speed of the car of Mindy = 32 mile/hour = 
1 mile = 1609.34 m
1 hour = 3600 seconds
Duration for her reaction last after student runs into street in front of her = 
Distance covered three -quarters of a second = d
d = 10.73 m ≈ 11 m
11 meters is her approximate reaction distance.
Answer: x = -0.3
Step-by-step explanation:
<u>Given expression</u>
1 - 3 (9x + 3) = 3x + 1
<u>Expand parentheses and apply the distributive property</u>
1 - 27x - 9 = 3x + 1
<u>Combine like terms</u>
(1 - 9) - 27x = 3x + 1
-8 - 27x = 3x + 1
<u>Subtract 3x on both sides</u>
-8 - 27x - 3x = 3x + 1 - 3x
-8 - 30x = 1
<u>Add 8 on both sides</u>
-8 - 30x + 8 = 1 + 8
-30x = 9
<u>Divide - 30 on both sides</u>
(-30)x / (-30) = 9 / (-30)
(-30)x / (-30) = 3 / (-10)
