Which are polynomials

Minchanka [31]

Given:

Given that there are 4 expressions.

We need to determine the expressions that are polynomials.

Option a: $-7x^2+\frac{5}{3x}$

In the second term of the expression, the constant is divided by a variable.

For an expression to be a polynomial, it should not divided by a variable.

Hence, the expression $-7x^2+\frac{5}{3x}$ is not a polynomial.

Thus, Option a is not the correct answer.

Option b: $-x^{2}+5 x$

The given expression satisfies the conditions of the polynomial.

Hence, the expression $-x^{2}+5 x$ is a polynomial.

Thus, Option b is the correct answer.

Option c: $6 x^{2}+5 x$

The given expression satisfies the conditions of the polynomial.

Hence, the expression $6 x^{2}+5 x$ is a polynomial.

Thus, Option c is the correct answer.

Option d: $x^{2}+5 x^{\frac{1}{5}}$

The second term of the expression contains the exponent $\frac{1}{5}$

For an expression to be a polynomial, the fractional exponent is not allowed.

Hence, the given expression $x^{2}+5 x^{\frac{1}{5}}$ is not a polynomial.

Thus, Option d is not the correct answer.

An expression is show below. (x 4/3) (x 2/3) what is the product of the two factors?

horrorfan [7]

Using FOIL, we multiply by the first polynomial to the other one in the parentheses. x times x is x^2. Now we have to multiply x by 2/3, which is 2/3x. Now we have to go to 4/3. We multiply 4/3 by the first polynomial in the other parentheses. 4/3 times x is 4/3 x. We then multiply 4/3 to the last polynomial in the other parenthesis. 4/3 times 2/3 is 8/9. Now, we add our terms. x^2 + 2/3x + 4/3x + 8/9. We can add 2/3x with 4/3x so we can simplify. 4/3+2/3= 6/3=2x. So our final answer will be x^2 + 2x + 8/9.

Just help me again for 2 times

ArbitrLikvidat [17]

Answer:

A. 86.7

first, the base. length x width.

it's square, so

5.1 x 5.1= 26.01

then the sides. formula for a triangle is base times height divided by 2.

5.1 x 5.95= 30.345 divided by 2 is 15.1725

there are 4 sides, so multiply times 4

4 x 15.1725= 60.69

now, add the base to the sides

26.01 + 60.69= 86.7

The mass of a jar is 750g when it is 1/2 filled with orange juice. The same jar has a mass of 625g when it is 1/4 filled with or

grandymaker [24]

Answer:

1875 g

Step-by-step explanation:

1/4=625g

3/4=x

Then cross multiply

1/4x=625*3/4

1/4x=468.75

Then divide both sides by .25

which is 1,875 grams
