Answer: ![A=15x^2+6x-48](https://tex.z-dn.net/?f=A%3D15x%5E2%2B6x-48)
Step-by-step explanation:
The area of a rectangle can be calculated with this formula:
![A=l*w](https://tex.z-dn.net/?f=A%3Dl%2Aw)
Where "l" is the length and "w" is the width.
You can identify from the figure that the length and the width of this rectangle are:
![length=3(x+2)\\width=5x-8](https://tex.z-dn.net/?f=length%3D3%28x%2B2%29%5C%5Cwidth%3D5x-8)
Then, you need to substitute this lenght and this width into
:
![A=3(x+2)(5x-8)](https://tex.z-dn.net/?f=A%3D3%28x%2B2%29%285x-8%29)
Now, apply Distributive property:
![A=(3x+6)(5x-8)\\\\A=15x^2-24x+30x-48](https://tex.z-dn.net/?f=A%3D%283x%2B6%29%285x-8%29%5C%5C%5C%5CA%3D15x%5E2-24x%2B30x-48)
Finally, you need to add the like terms. Then, you get:
![A=15x^2+6x-48](https://tex.z-dn.net/?f=A%3D15x%5E2%2B6x-48)
20 because there are many more
Answer: x=12, x=-3
Step-by-step explanation: For this factored problem, you see that -36 is negative, as well at -9. This shows you that you need to find two numbers that multiply to get -36, and add up to get -9. Two numbers that both satisfy these requirements are -12 and 3. They multiply to get -36, and add to get -9.
Once you have found your values, you plug them into (x+/- __)(x+/- __), which is (x-12)(x+3).
But since the problem asks you to find the zeroes, you set each factor equal to zero, like this:
x-12=0 and x+3=0
Then solve and you have you answer!
