Answer:
20.5 is the answer!! all you have to do is add em.
Answer:
-a(a+4)/(16 - a²)
Step-by-step explanation:
a/(a - 4) Multiply by (a + 4)/(a + 4)
= a(a + 4)/[(a – 4)(a + 4)] Multiply the denominatorator terms
= a(a + 4)/(a² - 16) Multiply by -1/(-1)
= -a(a+4)/(-a² + 16) Reorder terms in denominator
= -a(a+4)/(16 - a²)
Answer:
The width which gives the greatest area is 7.5 yd
Step-by-step explanation:
This is an application of differential calculus. Given the area as a function of the width, we simply need to differentiate the function with respect to x and equate to zero which yields; 15-2x=0 since the slope of the graph is zero at the turning points. Solving for x yields, x=7.5 which indeed maximizes the area of the pen

Answer:</h2>
Option: D is the correct answer.
The property which is illustrated by the given statement is:
D. Identity Property of Addition
<h2>
Step-by-step explanation:</h2>
We know that an identity is a value which when added to any element of the set gives the resultant as the element itself.
Also, we know that the identity under addition is always: zero.
Because when zero is added to any number then the resultant is the number itself i.e. adding zero does not affect the value.
Hence, by the Identity Property of Addition we have:
0 + x = x
