Answer:

The value of x is 9 ,  

And The measure of each sides of equilateral i.e QR , RS , QS is 35  .

Step-by-step explanation:

Given as :

Triangle QRS is an equilateral triangle  

The side of triangles are , QR , RS , QS

Now, According to question

QR = 2 x + 17

RS  = 6 x - 19

QS = 4 x - 1

∵ The Triangle is equilateral , then all sides are equal

So , QR = RS = QS

Or, 2 x + 17 = 6 x - 19 = 4 x - 1

Now, 2 x + 17 = 6 x - 19

So, 17 + 19 = 6 x - 2 x

Or, 36 = 4 x

∴   x = \frac{36}{4}

I.e x = 9

So, the measure of side QR = 2 x + 17 = 2 × 9 + 17

Or, the measure of side QR = 35

The measure of side RS  = 6 x - 19 = 6 × 9 - 19

Or, The measure of side RS  = 35

The measure of side QS =  4 x - 1 = 4 × 9 - 1

Or , The measure of side QS = 35

Hence The value of x is 9 ,  

And The measure of each sides of equilateral i.e QR , RS , QS is 35  . Answer

Nat2105 [25]
So, We Have A Rate That We Need To Simplify. We Have:
88 students for every 4 classes
So, We Need To Simplify This Rate. In Order To Do This, We Need To Change Is To A Fraction. It Is:
88 students
---------------
  4 classes

Now, We Have To Simplify. We Can Do That By Remembering How To Simplify Fractions.

So,
88 ÷ 2 =  44   ÷ 2  =   22 students
---            ---               ---------------
 4  ÷ 2 =   2    ÷ 2  =           1

So, The Unit Rate For 88 Students For 4 Classes Is:

Can someone help me with this?
Westkost [7]

Answer:

A=10 cm

B=5 cm

Area of square = 25 cm

Step-by-step explanation:

Since that is an equilateral triangle based off the fact that all the sides are the same variable (a) then that means 30 divided by 3 which equals 10. So now we know that a = 10. Lets input that information for the rectangle. Since there are 2 a's that equals 20 and the perimeter is 30 so b has to be 5 since 5 times 2 is 10 plus 20 equals 30. so now we know that a=10 and b=5 so our squares sides are all 5. The area of the square is 25

The diagonal of a square has length 10√2. Find the area of the square.
alex41 [277]

Answer: A = 100 square unit

Step-by-step explanation:

The formula for calculating the area of a square when the diagonal is given is :

Area = d^{2} / 2

That is :

A = \frac{(10\sqrt{2})^{2}}{2}

A = \frac{100(2)}{2}

A = 100 square unit
