Define x :
------------------------------------------------------
Let the width be x.
------------------------------------------------------
Find Area of the walkway :
------------------------------------------------------
Area = 30x + 30x + 20x + 20x + 4x²
Area = 100x + 4x²
------------------------------------------------------
Find cost of the walkway in term of x:
------------------------------------------------------
1m² = $10
100x + 4x² = 10(4x² + 100x)
(100x + 4x²)m = $(40x² + 1000x)
------------------------------------------------------
Find Width of the walkway :
------------------------------------------------------
The budget is $6000
40x² + 1000x = 6000
40x² + 1000x - 6000 = 0
x² + 25x -150 = 0 //Divide by 40 through
(x - 5)(x + 30) = 0 //Factorise
x = 5 or x = -30 (Rejected, width cannot be negative)
------------------------------------------------------
Answer: The width can be 5m wide.

If the backpack weighs 120 N, then the equivalent
weight in pounds is about 26.98 .
All that business about lifting and joules of work is
completely irrelevant to this question.
If n is odd then its cube is also odd because odd times odd is odd. When we add 5, an odd number, we get an even number.
If n is even, its cube is also even so adding an odd number makes the sum odd. So if the expression is odd, n must be even.
3 km north.
the east and west cancel out and the 5 north being greater than the two south leave you to only have to subtract the 2 south from the 5 north
Answer:
m = 4.7
Step-by-step explanation:
If you plug in these values in the slope formula, this is what happens:)
