1.Which expressions are polynomials? Select each correct answer. Pick more then one.

madreJ [45]

If all the power of the variables are greater than or equal to zero, then the expression is a valid polynomial.

So,

$7x^{7}-x-5$

$35x^{2}$

$\frac{x}{5}+2$

are polynomials.

$x^{2} -x\sqrt{2}$

2 + s

$4x^{2} +y$

are all polynomials.

If the degree of the polynomial is 3, then it is a cubic polynomial. If the number of terms of a polynomial is 3, then it is a trinomial.

Hence, $-5x^{3}-4x+1$ is a cubic trinomial.

The highest power is the degree.

Hence, degree of the polynomial is 2 + 4 = 6.

The distance from home plate to left field in a model of a baseball stadium measures 16.4 in. The scale of the model to the actu

Katen [24]

Answer:

317

Step-by-step explanation:

Since the ratio is 1:232, multiply 232 by 16.4:

$232*16.4=d$

$d=3804.8 in$

Divide by 12 to find the feet

$3804.8$ ÷ $12=d$

$d=317.066$

Round to the nearest foot

$d=317$
