Hello : here is a solution
Answer:
there are no expressions in the question, so I can't help you. Can you post the expressions?
I just did this question!
Answers:
1) <em>same side interior angles</em>
2) (3x+4)+(2x+11) = 180
3) 77
<span>We let x be the length and y be the width of the rectangle. Then,
Perimeter = 2x + 2y
100 = 2x + 2y
50 = x + y
y = 50 - x
Area = xy
A = x(50 - x)
A = 50x - x^2
We then take the derivative; set it equal to zero:
A ' = 50 - 2x
0 = 50 - 2x
2x = 50
x = 25
y = 50 - x
y = 50 - 25
y = 25
Therefore, the dimensions are 25 and 25.</span>
