A= L x W
Square has 4 equal sides
Which means the length and width are the same number

x^2= 81
X=9

9+9+9+9=36

Perimeter=36

Think About a Plan Write an indirect proof.
Alekssandra [29.7K]

1) Either \ell \parallel p or \ell ∦ p (only two possibilities)

2) Assume \ell \parallel p (one of two possibilities)

3) \angle 1 \cong \angle 2 (if two parallel lines are cut by a transversal, the corresponding angles are congruent)

4) But \angle 1 is not congruent to \angle 2 (given)

5) So \ell ∦ p (only other possibility)

A die is rolled twice. What is the probability of showing a 1 on the first roll and an even number on the second roll?
Ivan

Answer:

1/12

Step-by-step explanation:

Okay, so this will be a compound probability question because there are two parts to the question.

Firstly, a die has 6 sides, and there is only one chance of getting a 1, so the probability would be 1/6.

Furthermore, there are 3 different even numbers on a 6-sided die, so that is 3/6, which can be simplified to 1/2.

Now, because this is a compound probability, we have to multiply 1/2 and 1/6 together, which would give us our answer of 1/12.

Dafna11 [192]

Answer:

x=14/5

Step-by-step explanation:

Group like terms

2x+8x+7=35

Add similar elements: 2x+8x=10x

10x+7=35

Subtract 7 from both sides:

10x+7−7=35−7

Simplify

10x=28

Divide both sides by 10

10x/10 =28/10

Simplify:

x=14/5

If QRST below is a rectangle, what is the measure of angle T + angle R?
GenaCL600 [577]
I can't see QRST and I'm wondering how far below it's located.

But I do know that ALL of the angles in EVERY rectangle are
right angles ... 90°  each.

So if QRST is really a rectangle, then any two of its angles
add up to  (2 · 90°)  =  180° .
