It looks like you have
tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = cot(x) + tan(x) + 1
but this is not an identity.
Take for instance x = 3π/4. Then
tan(3π/4) = -1
cot(3π/4) = -1
so that
tan²(x) / (1 - tan(x)) + cot(x) / (1 - tan(x)) = 0
while
cot(x) + tan(x) + 1 = -1
and of course 0 ≠ -1.

There are 52 crayons in a box. There are 10 boxes in a carton. Mr. Johnson ordered 5 cartons of crayons for the school. How many crayons did he get?
Answer:
2,600 crayons
Step-by-step explanation:
10 boxes in a carton
5 cartons
10x5=50
52 crayons in a box
52x10=2,600 crayons
:)
Answer:
2,600
Step-by-step explanation:
If there are 52 crayons in a box, and 10 boxes in each carton, we know that there are 520 crayons in one carton. (52 x 10) If Mr. Johnson ordered 5 cartons,
520 x 5= 2,600. So, he would get 2,600 crayons.

Find the value of y, and then find all angles, pls help quick
Answer:
see explanation
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angle.
146° is an exterior angle of the triangle, then
5y + 3 + 4y + 8 = 146
9y + 11 = 146 ( subtract 11 from both sides )
9y = 135 ( divide both sides by 9 )
y = 15
Then
∠ A = 5y + 3 = 5(15) + 3 = 75 + 3 = 78°
∠ B = 4y + 8 = 4(15) + 8 = 60 + 8 = 68°
∠ C = 180° - (78 + 68)° ← sum of angles in triangle = 180°
∠ C = 180° - 146° = 34°

A) chaim used an invalid reason to justify the congruence of a pair of sides or angles.
B) chaim only established some of the necessary conditions for a congruence criterion.
C) chaim established all necessary conditions, but then used an inappropriate congruence criterion.
D) chaim used a criterion that does not guarantee congruence.
Plz help
The error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.
What is the Side-side-side Congruence Theorem (SSA)?The SSA congruence theorem only exist and holds true, only if the congruence non-included angles in both triangles are either obtuse or right angles and have two pairs of congruent sides.
Thus:
The two triangles given have a pair of non-included congruent angles that are less than 90 degrees.
Therefore, the error Chaim made in his proof is: D. Chaim used a criterion (SSA) that does not guarantee congruence.

I believe (x+5)(x-2) would be equal though.
Step-by-step explanation:
(x-5)(x+2) = x²+2x-5x-10
simplify:
x²-3x-10 ≠ x²+3x-10
(x)(x+3) = x²+3x
simplify:
x²-3x ≠ x²+3x-10
(x+3)(x-10) = x²-10x+3x-30
simplify:
x²-7x-30 ≠ x²+3x-10

In this experiment, you will be using two coins as a simulation for a real-world compound event.
Suppose that a family has an equally likely chance of having a cat or a dog. If they have two pets, they could have 1 dog and 1 cat, they could have 2 dogs, or they could have 2 cats.
1. What is the theoretical probability that the family has two dogs or two cats?
A dog or a cat will have a 50/50 chance of being adopted. There are three options: 50 percent for one dog and one cat, 25 percent for two dogs, and 25 percent for two cats. Adding the probabilities of finding two of the same dogs gives you a 50 percent shot.
2. Describe how to use two coins to simulate which two pets the family has.
You will have two fair sided coins if you used two coins to simulate the potential results of the family's dogs. Each coin will have one side with a dog and one with a cat (or heads and tails, where you would assign each pet a side of the coin).
3. Flip both coins 50 times and record your data in a table like the one below.
Result Frequency
Heads, Heads 15
Heads, Tails 9
Tails, Heads 19
Tails, Tails 7
Total 50
4. Based on your data, what is the experimental probability that the family has two dogs or two cats?
22/50.
5. If the family has three pets, what is the theoretical probability that they have three dogs or three cats?
50%.
6. How could you change the simulation to generate data for three pets?
You could add another coin.

The probability of the family having two dogs or two cats is 1/2 or 50%.
What is probability?It is the chance of an event to occur from a total number of outcomes.
The formula for probability is given as:
Probability = Number of required events / Total number of outcomes.
Example:
The probability of getting a head in tossing a coin.
P(H) = 1/2
We have,
The theoretical probability of the family having two dogs or two cats can be calculated as follows:
P(D) be the probability of having a dog
P(C) be the probability of having a cat.
Since the family has an equally likely chance of having a cat or a dog, we have:
P(D) = 1/2 and P(C) = 1/2
The probability of having 2 dogs is:
P(D) x P(D) = (1/2) x (1/2) = 1/4
The probability of having 2 cats is:
P(C) x P(C) = (1/2) x (1/2) = 1/4
The theoretical probability of the family having two dogs or two cats is:
P(2 dogs or 2 cats).
= P(2 dogs) + P(2 cats)
= 1/4 + 1/4
= 1/2
Thus,
The probability of the family having two dogs or two cats is 1/2 or 50%.

Just by looking at the question x + 6 + 2x = 2x + 6 + 4 so what does x equal and why?
I need help fast!
Answer:
x = 4
Step-by-step explanation:
x + 6 +2x = 2x + 6 + 4
combine like terms:
3x + 6 = 2x + 6 + 4
add numbers:
3x + 6 = 2x + 10
subtract 6 on both sides:
3x + 6 - 6 = 2x + 10 - 6
3x = 2x + 4
subtract 2x from both sides:
3x - 2x = 2x - 2x + 4
x = 4
short explanation:
if you look at the equation, both sides have 6 and 2x which would cancel each other out. That would leave x = 4

toddler after school, usually going to a
local playground. You notice that each
swing on the swing set takes nearly the
same amount of time, about 3.7 seconds
(1). Use the pendulum formula below to
find out how long (ft) the swing is. Round
your answer to the nearest tenths place.
T/2π = √L/32
3.7 / 2 π = 0.588873289
0.588873289² = L / 32
0.34677175 = L/32
