♡ Firstly , Here are some of the questions & their answers which should be known before simplifying the given expression :
Q. Do I have to change the sign of each term of second expression while subtracting ?
Ans : Yep! While subtracting , sign of each term of the second expression changes whereas In addition , sign of each term in the expressions remains unchanged.
Q. What do you mean by Like terms & Unlike terms ?
Ans : Well , Like terms are those which have the same base whereas Unlike terms are those which have the different base [ For eg : In 4x , 2y , 3x & 4y , 4x & 3x are like terms and 2y and 4y are like terms ]. Also Remember : Only coefficients of like terms can be added or subtracted.
The Question / Answer part ends up here. Now , Let's get started for simplifying the given expression :

Which of the pairs of angles are vertical angles and thus congruent? ∠A and ∠G ∠A and ∠B ∠C and ∠F ∠D and ∠H
Answer:
∠A and ∠G is the pair of vertical angles.
Step-by-step explanation:
From the figure attached,
Two lines 'm' and 'n' are two parallel lines. These lines intersect a horizontal line 'l'.
Since, "Pair of opposite angles formed at the point of intersection are the vertical angles and equal in measure."
Therefore, Opposite angles ∠A ≅ ∠G, ∠B ≅ ∠H, ∠C ≅ ∠E and ∠D ∠F are the vertical angles.
From the given options,
∠A and ∠G is the pair representing the pair of vertical angles and thus congruent.

The graph shows the total number of participants in a town's recreation program at the end of every year since the year 2000. The line of best fit for the data is given by the equation =13+50, where y is the total number of participants x years after the beginning of the year 2000.
Which statement correctly interprets the slope of the line of best fit?
A. The rate of change is 1 new participant every 13 years.
B. The rate of change is 13 new participants every 13 years.
C. The rate of change is 13 new participants every year.
D. The rate of change is 50 new participants every year.
Answer:
B
Step-by-step explanation:
Answer:
The rate of change is 13 new participants every year.
Step-by-step explanation:
y=13x+50
This is in the form y = mx+b where m is the slope and b is the y intercept
x is the number of years so for every year increase we gain 13 new participants

Step-by-step explanation:
25 points! Please help!
Answer:
17.5(D)
Step-by-step explanation:
So, lets see:
Every 5 minutes, Raul answers 22 questions.
The test has 77 questions.
We must figure out the time it takes to answer all 77 questions.
To do this, lets first divide the total questions by the questions answered per 5 minutes:
77 / 22
=
3.5
I got 3.5 knowing that 3x22 is 66, and half(0.5) of 22 is 11, and 11 plus 66 is 77.
So, the 3.5 is how many times he answrs 22 questions in five minutes.
To make a bit more sense, basically we have to multiply the 5 minutes by the 3.5:
3.5*5
=
17.5
We know that 3 times 5 is 15. Half(0.5) of 5 is 2.5, so 15+2.5 is 17.5.
So the answer is that for the 77 quesitons, it takes 17.5 minutes

3(MC) = SC
=====================================================
Explanation:
The three medians intersect at the centroid, which is point M in this case. The intersecting medians subdivide themselves in the ratio 2:1
This means that SM is twice as long as MC. We can say SM = 2MC
Then by the segment addition postulate, we know that:
SC = SM + MC
SC = 2MC + MC
SC = 3MC
3(MC) = SC
So having three copies of MC glued together will form segment SC.
The same idea applies for the other medians also (EK = 3EM and RL = 3ML).

Which term describes a fraction that has a polynomial in its numerator and denominator?
Answer:
Rational expression
Step-by-step explanation:
The experiment proceeded as normal, with the experimental group hearing about the potential presence of a gun as the confederates left the study and the control group not hearing about the gun. Unfortunately, word spread around campus about a man with a gun who stole a laptop during a study. Unknown to the study researchers, many potential participants participated in the research anyway, and kept an eye out for a gun, knowing that they might be asked about it. The researchers found that those in the experimental group did not differ from those in the control group about the likelihood of a gun. That is, the mean score that a gun was present during the second interview was similar for the experimental group (M = 67%, SD = 12.4%) and the control group (M = 63%, SD = 11.16%).

Answer:
The answer is "The threat to internal validity is mortality".
Step-by-step explanation:
It signifies that while in terms of your study, persons were "morning." It usually signifies when people leave the studies. There will be only likely if indeed the experiment lasts a long period that it'll be a substantial danger to validity and reliability because the chance for drops increases. Eight content validity risks are history, maturity, instrument, test, choice, average regress, human engagement, and mortality.

If the farmer has 180 feet of fencing, what are the dimensions of the region with the largest area?
Answer:kind of hard try 3x-x+2=4
Step-by-step explanation:
The dimensions of the region with the largest area is length=90 feet and width=45 feet.
Given that, three of the sides will require fencing and the fourth wall already exists.
What is the perimeter of a rectangle?The perimeter of a rectangle is the total distance of its outer boundary. It is twice the sum of its length and width and it is calculated with the help of the formula: Perimeter = 2(length + width).
Let the length of a wall be l and the width of a wall be w.
So, l+2w=180
⇒ l=180-2w
Area of a rectangle = Length×width
A(w)= (180-2w)×w
= 180w-2w²
The value of 'w' for which the derivate of the area function is zero will yield the maximum area:
A(w)=180w-2w²
⇒ A'(w)=180-4w
⇒ 180-4w=0
⇒ 4w=180
⇒ w=45 feet
So, l=180-2w =90 feet
Therefore, the dimensions of the region with the largest area is length=90 feet and width=45 feet.
