The greatest common factor of 18 and 42 is: 02 6 09 18

Alex Ar [27]

Answer:

Step-by-step explanation:

We can obtain the greatest common factor by listing the factors of the 2 numbers, that is

Factors of 18 are 1, 2, 3, 6, 9, 18

Factors of 42 are 1, 2, 3, 6, 7, 14, 21, 42

The common factors are 1, 2, 3, 6

The greatest common factor is 6

Find the area of the regular polygon

Y_Kistochka [10]

Answer:

A = 374.123 ft^2

Step-by-step explanation:

First, lets calculate the perimeter:

Perimeter (p) = side length (s) * number of sides (n)

$p = s * n$

$p = 12 * 6$

$p = 72$

Next, lets find the apothem, which is the shortest length from any side to the middle. It's like the radius in a circle, but more complicated.

Apothem (a) = side length (s) / ( 2 * tan(180/number of sides (n)) )

$a = \frac{s}{2 * tan (\frac{180}{n} )}$

$a = \frac{12}{2 * tan (\frac{180}{6} )}$

$a = \frac{12}{2 * \frac{\sqrt{3} }{3}}$

$a = \frac{12}{\frac{2\sqrt{3} }{3}}$

$a = \frac{12*3}{2\sqrt{3}}$

$a = \frac{6*3}{\sqrt{3}}$

$a = \frac{18}{\sqrt{3}}$

Now, finally, to find the area of a regular polygon, we use the following equation:

Area (A) = ( apothem (a) * perimeter (p) ) / 2

$A = \frac{a * p}{2}$

$A = \frac{\frac{18}{\sqrt{3} } * 72}{2}$

$A = \frac{18}{\sqrt{3}} * 36$

$A = \frac{640}{\sqrt{3}}$

Turning into a decimal:

$A = 374.123 ft ^2$

What is the answer Factorise: 2x² +7x+6.

Mila [183]

Answer:

2x + 3 )(x + 2 )

Step-by-step explanation:

2x² + 7x + 6

Find two numbers multiplied together to get 6

and if you multiply one by 2, the answer is 7:

Tested:

6 & 1 but 6 · 2 + 1 = 13 or 6 + 2 · 1 = 8 No

2 & 3 and 2 · 2 + 3 = 7 Yes

2x² = 2x & x

all signs are positive

trinomial factoring ( )( )

( + )( + )

2 and 3 are the numbers to use (2x + 3 )(x + 2 ) or (2x + 2) (x + 3)

The largest number goes with the 2x.

Therefore (2x + 3 )(x + 2 )

Check 2x(x + 2) + 3(x + 2)

2x² + 4x + 3x + 6

2x² + 7x + 6 checked
