Answer:
The length is 15 yards
Step-by-step explanation:
Given
Represent the width with W and length with L: So
Required
Determine the length of the rectangle:
Area is calculated as thus:
Substitute 3W - 12 for L and 135 for Area
Reorder:
Divide through by 3
Expand:
or 
or 
But width can't be negative
So:
Recall that:
<em>Hence, the length 15 yards</em>

Answer C. 95
<h3>
Answer: B. 781.6 feet approximately</h3>
=======================================================
Work Shown:
The horizontal portion is 400+166 = 566 feet. Label this as 'a', so a = 566. The vertical side is unknown, so b = x. The hypotenuse is c = 965
Use the pythagorean theorem
a^2+b^2 = c^2
566^2+x^2 = 965^2
x^2 = 965^2 - 566^2
x = sqrt( 965^2 - 566^2 )
x = 781.58108984289 which is approximate
x = 781.6 feet when rounding to one decimal place
Answer:
-3
Step-by-step explanation:
Given the function f(x) = -(-x)
we want to evaluate f(-3)
What we do simply here is substitute the value of -3 for x in the equation
That would be ;
f(-3) = -(-(-3)) = -(3) = -3
