What is the value of x if the perimeter of both shapes is the same?
AveGali [126]

The value of x is: \frac{4}{3}

<u><em>Recall</em></u>:

Perimeter of a shape is the sum of all its sides

<em>Thus</em>:

Perimeter of the triangle = x + x +x+ 4 = 3x + 4

Perimeter of the rectangle = 2(2x) + 2(x) = 4x + 2x = 6x

We are told that the perimeter of both shapes are equal. Set both perimeters equal and solve for x.

3x + 4 = 6x

<em>Add like terms</em>

<em />4 = 6x - 3x\\4 = 3x

<em>Divide both sides by 3</em>

<em />\frac{4}{3} = x\\x = \frac{4}{3}

The value of x = \frac{4}{3}

You like math then here
Igoryamba

Answer:

-8b + 9 - 5k

Step-by-step explanation:

I am assuming the blue highlighted portion is your answer, and is not a part of the initial question

(-4b + 15 - 7k) - (6 + 4b - 2k)

Combine like terms

-4b - + 4b

Negative + Positive = Negative

-4b - 4b = -8b

15 - 6 = 9

-7k - - 2k

Negative + Negative = Positive

-7k + 2k = -5k

Put them all together:

0b + 9 - 5k

Simplify

-8b + 9 - 5k

I got the same answer as you (just in a different order)

TiliK225 [7]

Answer:

This is math????

Step-by-step explanation:

A, because this shows that jackie is just making sure that the doctor didn't forget anything in a not rude way. The other ways she is kinda asserting her thoughts as Right and  the doctor is wrong, or she assumes he knows what he is doing when he might have actually forgotten.

Solve the value for v.
NemiM [27]

Answer:

Hey mate !!

Your answer is so simple :)

<h2>V= 9°</h2>

Go through the explanation to understand.

Step-by-step explanation:

In the given question,

We see that 105° and it's adjacent angle (i.e. 8v+3° ) forms a supplementary angle. Which means the sum of 8v+3°+105° is 180°

<h3>Therefore,</h3>

According to the question

105 + 8v + 3 = 180

=  > 105 + 8v = 180 - 3

=  > 8v =  177 - 105

=  > 8v = 72

=  > v =  \frac{72}{8}

=  > v = 9

Answer the value of v is 9° .

Hope it helps you!!
