In B 5^2 = 25. There is no x anywhere.
In C f(x) = 2/x is a function of a reciprocal, not a quadratic.
In D f(x) = 2x^3 + 3x^2 - 5 is a cubic. A cubic is not a quadratic. The highest power of a quadratic is x^2
That leaves A. When you expand the brackets, you get
3(x^2 + 3x- 4x - 12)
2(x^2 - x - 12) when you remove the brackets you get
2x^2 - 2x - 24. The highest power of x is x^2. This is your quadratic.

In triangles BCG and BPE
![\angle BCG \cong \angle BPE (Alternate \: \angle 's) \\\angle GBC \cong \angle EBP (Vertical \: \angle 's) \\\therefore \triangle BCG \sim \triangle BPE (AA \: postulate) \\\\\therefore \frac{BE}{BG} =\frac{PE}{GC} =\frac{BP}{BC}...(csst)\\\\\therefore \frac{BE}{425} =\frac{PE}{375} =\frac{225}{325}\\\\\therefore \frac{BE}{425} =\frac{PE}{375} =\frac{9}{13}\\\\\therefore \frac{BE}{425} =\frac{9}{13}\\\\BE =\frac{9\times 425}{13}\\\\BE =\frac{3,825}{13}\\\\BE = 294.23\: ft \\\\\&\\\frac{PE}{375} =\frac{9}{13}\\\\PE =\frac{9\times 325}{13}\\\\PE =\frac{3,375}{13}\\\\PE = 259.615385 \\\\PE = 259.62 \: ft\\\\](https://tex.z-dn.net/?f=%5Cangle%20BCG%20%5Ccong%20%5Cangle%20BPE%20%20%28Alternate%20%5C%3A%20%5Cangle%20%27s%29%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Cangle%20GBC%20%5Ccong%20%5Cangle%20EBP%20%20%28Vertical%20%5C%3A%20%5Cangle%20%27s%29%20%5C%5C%3C%2Fp%3E%3Cp%3E%5Ctherefore%20%5Ctriangle%20BCG%20%5Csim%20%5Ctriangle%20BPE%20%20%28AA%20%5C%3A%20postulate%29%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Ctherefore%20%5Cfrac%7BBE%7D%7BBG%7D%20%20%3D%5Cfrac%7BPE%7D%7BGC%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7BBP%7D%7BBC%7D...%28csst%29%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Ctherefore%20%5Cfrac%7BBE%7D%7B425%7D%20%20%3D%5Cfrac%7BPE%7D%7B375%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7B225%7D%7B325%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5Ctherefore%20%5Cfrac%7BBE%7D%7B425%7D%20%20%3D%5Cfrac%7BPE%7D%7B375%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7B9%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E%5Ctherefore%20%5Cfrac%7BBE%7D%7B425%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7B9%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3EBE%20%3D%5Cfrac%7B9%5Ctimes%20425%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EBE%20%3D%5Cfrac%7B3%2C825%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EBE%20%3D%20294.23%5C%3A%20ft%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%5C%26%5C%5C%3C%2Fp%3E%3Cp%3E%5Cfrac%7BPE%7D%7B375%7D%20%3C%2Fp%3E%3Cp%3E%3D%5Cfrac%7B9%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3EPE%20%3D%5Cfrac%7B9%5Ctimes%20325%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EPE%20%3D%5Cfrac%7B3%2C375%7D%7B13%7D%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EPE%20%3D%20259.615385%20%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3EPE%20%3D%20259.62%20%5C%3A%20ft%5C%5C%5C%5C%3C%2Fp%3E%3Cp%3E%3C%2Fp%3E%3Cp%3E)
Answer:
311 I ALREADY TOKK THIS TEST
Step-by-step explanation:
The given expression above is non linear
<h3>Polynomial functions</h3>
Given the polynomial functions expressed as:
- 5 + 9x + 7 + 2x^4
- 14 + 9x + 2x^4
There are 3 terms in all. From the functions, the term with variables are 9x and 2x^4 and the constant is 14, hence there are three terms with coefficients, and they are 14, 9 and 2
The given expression above is non linear due to the degree of 4 present in the function
