Answer:

Step-by-step explanation:

Given that Amir is sorting his stamp collection. He has made a chart of what countries the stamps are from

He got results as

France 1/3  

Morocco 5/12  

Spain 1/6

To find out what fraction of Amir's stamps are from France, Morocco, or Spain, we have to simply add the three as there is common element between any two pairs

Hence answer is

\frac{1}{3} +\frac{5}{12} +\frac{1}{6}\\ =\frac{11}{12}

In the figure shown PS = RQ. which theorem can be used to prove Triangle SQR = Triangle QSP?
Nuetrik [128]

Answer:

HL (hypotenuse leg)

Step-by-step explanation:

From the diagram, we have two sides that are congruent

The side QS is common to both triangles

Also, we have it that the side PS and QR are congruent

What this mean is that we have two sides that are already the same

Now, looking at the right angle position in both, we can see that QR and PS represents the hypotenuse of individual right angles

Using the HL congruence statement, since we have it that the hypotenuse one side is already congruent, we can conclude that the last side too is congruent and as such both triangles are congruent to each one another

How do you solve (2x + 8 )2 =64
Drupady [299]

Answer:

x = 12

Step-by-step explanation:

  1. Write in a different way: 2(2x + 8) = 64
  2. Apply the distributed property, so it now looks like this: 4x + 16 = 64
  3. Subtract 16 from each side, so it now looks like this: 4x = 48
  4. Divide each side by 4 to cancel out the 4 next to x. It should now look like this: x = 12

I hope this helps!

Answer:

The dimensions are:

3(2x+1) by (7x+5)

Step-by-step explanation:

The area of the rectangle is given as

A=42x^2+51x+15

The factored form of this quadratic trinomial gives the dimensions of the rectangle.

We factor 3 first to obtain;

A=3(14x^2+17x+5)

We split the middle term to get;

A=3(14x^2+10x+7x+5)

We factor within the parenthesis to get;

A=3(2x(7x+5)+1(7x+5))

We factor further to get;

A=3(2x+1)(7x+5)

The dimensions are:

3(2x+1) by (7x+5)

Then the perimeter will be

2(6x+3+7x+5)=26x+16\:\:\:\boxed{\sqrt{} }
