The question is telling you that the length of the rectangle is 3 metres more than twice the width.

So let:

<em>w= width</em>

<em>L= length</em>

Because the length is 3 metres more than twice<em> </em>the width: <em>L= </em><em>2</em><em>w+</em><em>3</em>


They also tell you the perimeter is 48 metres.

<em>P= L+L+w+w</em>

So the equation of the perimeter is:

<em>48= (2w+3)+(2w+3)+2w +2w</em>

<em>48= 2(2w+3) + 4w</em>


To find w, expand and simplify.

<em>48= 4w+6+4w</em>

<em>48= 8w + 6</em>

<em>42= 8w</em>

<em>5.25=w</em>


Now that you know the width, plug in the value into the length equation:

<em>L= 2w+3</em>

<em>L=2(5.25)+3</em>

<em>L=10.50+3</em>

<em>L=13.5</em>


If I am wrong let me know! I hope this helps.

Find the value of x posting picture
mafiozo [28]

Answer:

<em>x = 9; Option C</em>

Step-by-step explanation:

If p ║q, we are provided with the following properties;

Same Side Interior / Exterior ∠s ⇒ supplementary,

Alternate Interior / Exterior ∠s ⇒ ≅,

Corresponding ∠s ⇒ ≅

If we are focusing on the measure of two alternate interior angles, say a and b, we can assign them as such;

a ⇒ 9x + 8, and b ⇒ 15x - 46

m∠ a = m∠ b ⇒ provided they are alternate interior ∠s,

9x + 8 = 15x - 46 ⇒ Add 46 on either side of equation,

9x + 54 = 15x ⇒ Subtract 9x from either side,

54 = 6x ⇒ Divide either side by 6,

<em>Solution; x = 9</em>

How long does it take you and students 2 and 3 to clean up a 12 ft. X 12 ft wall covered in graffiti? Besides the answer (be spe
Ostrovityanka [42]

Answer:

At a combined speed of 6 in/min, it takes us 24 mins to clean the wall

Step-by-step explanation:

Since the question did not provide the speed with which each student cleans, we can make assumptions. This is so that we can solve the question before us

Assuming student 1 cleans at a speed of 2 inches per minute, student 2 cleans at a speed of 2½ inches per minute & student 3 cleans at a speed of 1½ inches per minute.

Let's list the parameters we have:

Height of wall (h) = 12 ft, Speed (student 1) = 2 in/min, Speed (student 2) = 2½ in/min, Speed (student 3) = 1½ in/min

Speed of cleaning wall = Height of wall ÷ Time to clean wall

Time to clean wall (t) = Height of wall ÷ Speed of cleaning wall

since students 1, 2 and 3 are working together, we will add their speed together; v = (2 + 2½ + 1½) = 6 in/min

1 ft = 12 in

Time (t) = h ÷ v = (12 * 12) ÷ 6 = 144 ÷ 6

Time (t) = 24 mins

What is the answer to 8(2× - 6) =96​
Arisa [49]

Answer:

the answer is 3

x= 3

Step-by-step explanation:

8(2× - 6) =96​

multiply 8 on the right side of equation we get

16x -48 = 96

16x= 96-48

16x = 48

divide by 16 on both side we get

simplify

16x / 16 = 48 / 16

x = 3

So that the value of x we get after the equation solved is x = 3

hopefully it will be brainliest for you

thank you !
