Write an expression to represent the length is 6 feet longer than the width
Ivenika [448]

Step-by-step explanation:

Let l be the length of the room, and w be the width.

If the length is 6 feet longer than twice the width, then we can say l = 2w+6

Knowing that the formula for the perimeter of a rectangle is P = 2l+2w, and knowing that P=144 ft, we can say that 2L + 2w= 144 ft.

To find the dimensions, we plug our value for l into our perimeter equation

This gives us the following equation: 144= 2(2w+6) + 2w, which simplifies to 144=4w+12+2w, which further simplifies to 144= 6w+12

To get w on one side of the equation, we subtract 12 from each side, which gives us 132=6w

Dividing each side by 6, we determine that w= 22 ft.

Plugging this value back into our first equation we see that l= 2(22)+6

So l= 50 ft.

So, the dimensions of the room are as follows: length is 50 ft., width is 22 ft.

I'm pretty sure the answer's one, but I need an expression. I will give brainiest to whoever answers this!!!
givi [52]

Answer:

0x+1 (or just 1)

Step-by-step explanation:

if non shaded/ white tiles are negative, and shaded positive expression would look like:

2x+4 and -2x-3

when simplified 2x-2x cancels out, and 4-3=1.

what is left over is just 1.

What is the equation of the graphed function?
masya89 [10]
The correct answer is A.) f(x)=\frac{-1}{3}x+1

This is because using slope intercept form (y=mx+b), we can solve.

m = slope
b= y-intercept

If you look at the graph, you can see the line crosses they y-axis at 1.

And if you follow the line using rise over run, you find that it is 1/3.
But because it is a negative line, it makes the slope negative.

Hope this helps!

If j = k, then j + 9 = k + 9 represents which algebraic property
sleet_krkn [62]

Answer:

c) The given  expression represents Addition Property of Equality.

Step-by-step explanation:

Here, the given expression is j = k

Now by ADDITION PROPERTY OF EQUALITY:

The property that states that if you add the same number to both sides of an equation, the sides remain equal.

So,  <u>  if A  = B  ⇒  A + </u><u>x </u><u> =  B + </u><u>x</u>

<u></u>

Now, here given that j = k

If we add the same number 9 on both the sides, the equation remains  undisturbed.

⇒   j + 9  = k + 9

Hence, the above expression represents Addition Property of Equality.
