Answer:

\mathrm{A.\:}x+2y=a

Step-by-step explanation:

In standard form ax+by=c, any point the line passes through will make the inequality true. We can simply use any point given to find the equation of the line:

We can write the following system of equations from two points from the table:

\begin{cases}d\cdot3a+e\cdot(-a)=f\cdot a\\d\cdot5a+e\cdot(-2a)=f\cdot a\end{cases}

Solving, we get:

For a \notin 0,

d=1,\\e=2,\\f=1

Therefore, our equation is:

dx+ey=fa,\\1x+2y=1a,\\\fbox{$x+2y=a$}.

MakcuM [25]

Answer: 234

Step-by-step explanation:

A golden rectangle is a rectangle whose length is approximately 1.6 times its width.

Mike Hallahan would like to plant a rectangular garden in the shape of a golden rectangle.

If he has "234"* feet of fencing is available, find the dimensions of the garden. *Makes more sense.

:

let w = the width of the garden

then

1.6w = the length

:

2(1.6w) + 2w = 234

3.2w + 2w = 234

5.2w = 234

w = 234/5.2

w = 45 ft is the width

and

1.6(45) = 72 ft is the length

:

:

Check

2(72) + 2(45) =

144 + 90 = 234

What s the factor of (x+3)(x+2)
Virty [35]
<span>Simplifying (x + 3)(x + 2)
 
Reorder the terms: (3 + x)(x + 2)
 
Reorder the terms: (3 + x)(2 + x)
 
Multiply (3 + x) * (2 + x) (3(2 + x) + x(2 + x)) ((2 * 3 + x * 3) + x(2 + x)) ((6 + 3x) + x(2 + x)) (6 + 3x + (2 * x + x * x)) (6 + 3x + (2x + x2))
 
Combine like terms: 3x + 2x = 5x (6 + 5x + x2)
 
Factor a trinomial. (3 + x)(2 + x)

Final result:
(3 + x)(2 + x)</span>
