Answer:
Step-by-step explanation:
180-96
180-96 = 84
96 + 84 = 180
Let the lengths of the sides of the rectangle be x and y. Then A(Area) = xy and 2(x+y)=300. You can use substitution to make one equation that gives A in terms of either x or y instead of both.
2(x+y) = 300
x+y = 150
y = 150-x
A=x(150-x) <--(substitution)
The resulting equation is a quadratic equation that is concave down, so it has an absolute maximum. The x value of this maximum is going to be halfway between the zeroes of the function. The zeroes of the function can be found by setting A equal to 0:
0=x(150-x)
x=0, 150
So halfway between the zeroes is 75. Plug this into the quadratic equation to find the maximum area.
A=75(150-75)
A=75*75
A=5625
So the maximum area that can be enclosed is 5625 square feet.
Answer:
Step-by-step explanation:
The correct answer for the first question is, what does the audience want to know? She wants the audience to know that she is preparing to write an article for his school newspaper. A thesis statement is a sentence that most likely explains the papers topic and knowing the audience will help her use the right words and connotations to provide the best report to her teacher.
