To find the dimensions you can just factor the equation...
x^2+4x-21
x^2-3x+7x-21
x(x-3)+7(x-3)
(x+7)(x-3) and this is equal to LW or WL
And note that x>3 for any possible solution.
Answer:-9√(11)
Step-by-step explanation:
5√(11) - 12√(11) - 2√(11)
Since they are all alike,as in they possess √(11),we can just add or subtract them through
-7√(11) - 2√(11)
-9√(11)

Answer:
30
Step-by-step explanation:
We note that 6 animals in 12 minutes is half as many animals as minutes. So, in 60 minutes, Naomi can make 30 balloon animals.
Answer:
The value of q that maximize the profit is q=200 units
Step-by-step explanation:
we know that
The profit is equal to the revenue minus the cost
we have
---> the revenue
---> the cost
The profit P(q) is equal to

substitute the given values



This is a vertical parabola open downward (because the leading coefficient is negative)
The vertex represent a maximum
The x-coordinate of the vertex represent the value of q that maximize the profit
The y-coordinate of the vertex represent the maximum profit
using a graphing tool
Graph the quadratic equation
The vertex is the point (200,-120)
see the attached figure
therefore
The value of q that maximize the profit is q=200 units
