What is permieter of the rectangle?<br><br>

Andreas93 [3]

The perimeter is adding all four sides together.

In a rectangle the two opposite sides are identical, so there are two sides 2 ft long and 2 sides 3.4 ft long.

Perimeter = 2 + 2 +3.4 + 3.4 = 10.8 feet.

Select the correct answer. which expression is equivalent to the given expression? assume the denominator does not equal zero. a

Alexxandr [17]

If the denominator does not equal 0, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$ $\frac{x^{10} y^{14}}{729}$

<h3>How to determine the equivalent expression?</h3>

The expression is given as:

$\frac{14x^4y^6}{7x^8y^2}$

Divide 14 by 7

$\frac{14x^4y^6}{7x^8y^2} = \frac{2x^4y^6}{x^8y^2}$

Apply the law of indices

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{6-2}}{x^{8-4}}$

Evaluate the differences in the exponents

$\frac{14x^4y^6}{7x^8y^2} = \frac{2y^{4}}{x^{4}}$

Hence, the equivalent expression of $\frac{14x^4y^6}{7x^8y^2}$ is $\frac{2y^{4}}{x^{4}}$

The equation y = 0.002x - 0.30 can be used to determine the approximate cost, y in dollars, of producing x items. How many items

NikAS [45]

Answer:

Company must not produce more than 193,650 units to keep cost as $387

Step-by-step explanation:

we are given with the cost function as

y = 0.002x - 0.30

where x is the number of items produced

We are asked to determine the number of items must be produced so that the cost of production does not go beyond $387

Hence

we put y = 387 and then solve the equation thus formed for x

y = 0.002x - 0.30

387 = 0.002x - 0.30

adding 0.30 on both sides

387+0.30=0.002x

387.30=0.002x

dividing both sides by 0.002

$\frac{387.30}{0.002}=x$

x=193,650

Company must not produce more than 193,650 units to keep cost as $387
