Find the area of the rug. DO NOT ROUND. what is the area?

Neporo4naja [7]

Answer:

28.26 ft²

Explanation:

$\sf area \ of \ circle = \pi r^2$

Here given diameter: 6 ft

radius: d/2 = 6/2 = 3 ft

========

area of rug:

$\dashrightarrow \ \pi (3)^2$

$\dashrightarrow \ 9\pi$

$\dashrightarrow \ 9(3.14)$

$\dashrightarrow \ 28.26 \ ft^2$

Solving these quadratics for x using complete the square 3x^2-4x-1=0. Show your work.

UkoKoshka [18]

Answer: x = (sqrt(7) + 2)/3 and
x = ( – sqrt(7) + 2)/3

Explanation:

3x^2 - 4x - 1 = 0

Divide both sides by 3:

3x^2/3 - 4/3x - 1/3 = 0/3
x^2 - 4/3x - 1/3 = 0
x^2 - 4/3x = 1/3
x^2 - 4/3x + (2/3)^2 = 1/3 + (2/3)^2
(x - 2/3)^2 = 1/3 + 4/9
(x - 2/3)^2 = 7/9

Sqrt both sides:

x - 2/3 = sqrt (7/9)
x - 2/3 = |sqrt(7)/3|

Set x -2/3 = sqrt(7)/3

=> x = (sqrt(7) + 2)/3

Set x - 2/3 = - sqrt(7)/3

=> x = ( - sqrt(7) + 2)/3

Steven wrote this equation. 4×18=418 Explain the error in Steven's reasoning. Find the correct product. Enter your explanation a

Thepotemich [5.8K]

Given:

Steven wrote this equation:

$4\times 18=418$

To find:

The error in Steven's reasoning and then find the correct product.

Solution:

We have,

$4\times 18=418$

This statement is incorrect because we cannot write product directly as Steven wrote.

We need to multiply the place values of each digit of first number with the place values of second number and then we need to add the resulted values.

$4\times 18=4\times (10+8)$
