Answer:
A = 2x²-3x-5
Step-by-step explanation:
Given that,
The length of the bedroom, l = (2x-5)
Width of the bedroom, b = (x+1)
We need to find an equation for the area of the bedroom. We know that,
Area of a rectangle = lb
Put all the values,
A = (2x-5)(x+1)
= 2x²+2x-5x-5
= 2x²-3x-5
Hence, the area of the bedroom is equal to 2x²-3x-5.
Answer:

Step-by-step explanation:
According to Rolle's Theorem, if f(a) = f(b) in an interval [a, b], then there must exist at least one <em>c</em> within (a, b) such that f'(c) = 0.
We are given that g(5) = g(8) = -9. Then according to Rolle's Theorem, there must be a <em>c</em> in (5, 8) such that g'(c) = 0.
So, differentiate the function. We can take the derivative of both sides with respect to <em>x: </em>

Differentiate:

Let g'(x) = 0:

Solve for <em>x</em>. First, divide everything by negative seven:

Factor:
<h3>

</h3>
Zero Product Property:

Solve for each case. Hence:

Since the first solution is not within our interval, we can ignore it.
Therefore:

And isosceles triangle always equals 180 degrees so to find the value of x what number would you need for the value to be 180
Answer:
x = -0.8
<CAD = -8
Step-by-step explanation:
10x + 4 = 5x - 4 (Clean up)
10x = -8 (Divide each side by 10)
x = -0.8
<CAD = 5x - 4
<CAD = 5(-0.8) - 4
<CAD = -4 - 4
<CAD = -8
The answer would be 4 divided by 2/3 = 6 tiles
