Which statement best describes the equation x5 + x3 – 14 = 0?

a. the equation is quadratic in form because it is a fifth-degree polynomial.

b. the equation is quadratic in form because the difference of the exponent of the lead term and the exponent of the middle term is 2.

c. the equation is not quadratic in form because it cannot be rewritten as a second-degree polynomial.

d. the equation is not quadratic in form because the exponent of the lead term is not the square of the exponent of the middle term.

It should be C.

cause you could multiply x a lot and that's a huge stretch so it wouldn't really work which makes it a straight line which also makes a linear equation so you could rewrite it as a quadratic but not really no its not a quadratic

C

Step-by-step explanation:

The equation x5 + x3 – 14 = 0 is a polynomial with three terms. This polynomial has as its highest exponent a 5 making it a 5th degree polynomial. This is not quadratic because a quadratic has as its highest exponent a 2 making it a second degree polynomial. Because the exponent of the leading term is 5, this cannot be written as a polynomial with degree 2. THe best answer choice which matches this analysis is C.

c.   x=2.4cm

step-by-step explanation:

similar triangles are triangles which have the same shape but not the same size. this means their angle measures are equal but their side lengths are not instead they are proportional. to solve, we will set up a proportion and solve.

a proportion is two equal ratios set equal to each other. we form the ratios by finding corresponding sides (sides which match to each other on both triangles by their position). out ratios will be one side of the small triangle over the corresponding side on the big triangle as shown below:

.

to solve the proportion, we'll cross multiply by multiplying numerator with denominator across the equal sign.
