Which value of c would make the following express completely factored? 8x+cy
Artist 52 [7]
The answer is B, 7.

\sf 8x+2y

We can factor a 2 out of this: \sf 2(4x+y)

\boxed{\sf 8x+7y}

We can't factor anything.

\sf 8x+12y

We can factor a 4 out of this: \sf 4(2x+3y)

\sf 8x+16y

We can factor an 8 out of this: \sf 8(x+2y)

So your answer is B, 7.

Solve the system by substitution. <br> −7x−10y= 40 <br> x=−2y
Harrizon [31]

Answer:

x= -20, y= 10

Step-by-step explanation:

Label the two equations:

-7x -10y= 40 -----(1)

x= -2y -----(2)

Substitute (2) into (1):

-7(-2y) -10y= 40

Expand:

14y -10y= 40

Simplify:

4y= 40

Divide both sides by 4:

y= 40 ÷4

y= 10

Substitute y= 10 into (2):

x= -2y

x= -2(10)

x= -20

Find the area of the regular polygon. Round to the nearest tenth.
mojhsa [17]

Given:

Side length = 12 in

To find:

The area of the regular polygon.

Solution:

Number of sides (n) = 6

Let us find the apothem using formula:

$a=\frac{s}{2 \tan \left(\frac{180^\circ}{n}\right)}

where s is side length and n is number of sides.

$a=\frac{12}{2 \tan \left(\frac{180^\circ}{6}\right)}

$a=\frac{6}{ \tan (30^\circ)}

$a=\frac{6}{ \frac{1}{\sqrt{3} }}

$a=6\sqrt{3}

Area of the regular polygon:

$A=\frac{1}{2}(\text { Perimeter })(\text { apothem })$

$A=\frac{1}{2}(6 \times 12)(6\sqrt{3} )

$A=\frac{1}{2}(72)(6\sqrt{3} )

A=216 \sqrt{3}

A=374.1 in²

The area of the regular polygon is 374.1 in².
