√2x^2 ·√4x

Answers

the answer is: 2x sqrt 2x

The expression √(2x²) · √(4x) is equivalent to the expression 2x√2x. Then the correct option is D.

What is an equivalent expression?

The equivalent is the expressions that are in different forms but are equal to the same value.

The expressions are given below.

√(2x²) and √(4x)

Then the product of the expressions √(2x²) and √(4x) will be

⇒ √(2x²) · √(4x)

The factor of 2x² will be

2x² = 2 · x · x

The factor of 4x will be

4x = 2 · 2 · x

Substitute in the expression, then the expression will be

⇒ √(2 · x · x) · √(2 · 2 · x)

We know that √x² = x and √4 = 2. Then the expression will be

⇒ x√2 · 2√x

⇒ 2x√2x

Thus, the expression √(2x²) · √(4x) is equivalent to the expression 2x√2x.

Then the correct option is D.

15points please help

Answers

Answer:The zeros are 6, -5, 9

Step-by-step explanation:

The zeros of the polynomial function are x = 6, x = -5, and x = 9. The correct option is A.

What are polynomials?

In mathematics, a polynomial is an expression that solely uses the operations of multiplication, addition, subtraction, and non-negative integer exponentiation of variables. It is made up of coefficients and indeterminates.

The zeros of the polynomial function are the values of x that make f(x) equal to zero.

The polynomial f(x) is written in factored form as:

f(x) = (x - 6)(x + 5)(x - 9)

The zeros of the polynomial are the values of x that make any of the factors equal to zero. Therefore, the zeros are:

x - 6 = 0, which gives x = 6

x + 5 = 0, which gives x = -5

x - 9 = 0, which gives x = 9

Thus, the zeros of the polynomial function are x = 6, x = -5, and x = 9.

Tara bought a silver coat rack originally priced at $375 but on sale for 20% off. After 12% sales tax, what was the total cost?

Answers

Answer:

$336

Step-by-step explanation:

1 - 20% = .8

1 * 12% = 1.12

375 * .8 * 1.12 = 336

The total cost was of $336.

--------------

This question is solved using percentages/proportions.

The original price is of $375.On sale for 20% off, which means that you pay 1 - 0.2 = 0.8 of the price.Sales tax of 12%, which means that the cost is also multiplied by 1 + 0.12 = 1.12.

Thus, the total cost will be given by:

[tex]C = 375 \times 0.8 \times 1.12 = 336[/tex]

The total cost was of $336.
