Answer:
![\huge\boxed{A=x^2+12x+35}](https://tex.z-dn.net/?f=%5Chuge%5Cboxed%7BA%3Dx%5E2%2B12x%2B35%7D)
Step-by-step explanation:
The formula of an area of a rectangle:
![A=lw](https://tex.z-dn.net/?f=A%3Dlw)
<em>l</em><em> - length</em>
<em>w</em><em> - width</em>
We have
![l=x+7\\\\w=x+5](https://tex.z-dn.net/?f=l%3Dx%2B7%5C%5C%5C%5Cw%3Dx%2B5)
Substitute:
![A=(x+7)(x+5)](https://tex.z-dn.net/?f=A%3D%28x%2B7%29%28x%2B5%29)
Use FOIL <em>(a + b)(c + d) = ac + ad + bc + bd</em>
<em></em>
<em></em>
combine like terms
![A=x^2+(5x+7x)+35\\\\A=x^2+12x+35](https://tex.z-dn.net/?f=A%3Dx%5E2%2B%285x%2B7x%29%2B35%5C%5C%5C%5CA%3Dx%5E2%2B12x%2B35)
1. Quadratic y=x^2
2. Linear y=X+7
3. Exp. Y= 1 times 2^x
4. Linear Y=4x
5. Linear Y= -5x+1
Answer:
x> -10
Step-by-step explanation:
in order to find what the value of X is you have to multiply the 5 of the denominator into the -6 which would make -30.
You would then divide by 3 in order to get x by itself and would get -30÷3= -10
therefore the answer should be greater than -10
