For example:
2x + 7 + 8x + 3
What you want to do is simply the expression
We can see that 2x and 8x are both coefficients
(A coefficient is a number that is going to be multiplied by a variable such as 3y, 2x, 7x and so on)
They are both like terms meaning that they can be combined
2x + 8x= 10x
Next, you want to see if you can combine anything else because our goal is to make the expression simplified.
7 and 3 can be combined because they are like terms
7+3= 10
Now that you have the new numbers I guess you can call it your answer should be
10x + 10
Hopefully this helps you answer the other questions. I did this lesson not too long ago so if you need help on anything else I can try to explain it.

Students who attend Anytown College pay either in-state or out-of-state tuition, depending on where they reside. The amount, I, spent on in-state tuition and the amount, O, spent on out-of-state tuition for a randomly selected student both follow a Normal distribution.
The mean and standard deviation of the sum S = I + O of tuition for a randomly selected pair of in-state and out-of-state students are μS = $6,348.75 and σS = $1,508.48.
Use the z-table to answer the question.
What is the probability that the sum of a randomly selected pair of in- and out-of-state students has a tuition charge of more than $8,000?

There is a triangle with sides measuring 30in, 30in and 25in. Is this a right triangle? Why or why not?
Answers
Answer:
No. In order to be a right triangle, the lengths of the 2 smaller sides must equal the length of the longest side.
In other words, these 3 sides must work with the Pythagorean theorem.
A^2 + B^2 = C^2
25^2 + 30^2 is NOT 30^2
This is a triangle, just not a right triangle.

Find the expected value of the winnings from a game that has the following payout probability distribution. Round to the nearest hundreath.
Answers
Step-by-step explanation:
Here, we want to calculate the expected value
What we have to do here is to multiply the probability by the payout value; after which we add all values
Thus, we have the payout value as;
1(0.12) + 4(0.2) +6(0.38) + 8(0.2) + 10(0.1)
= 0.12 + 0.8 + 2.28 + 1.6 + 1
The expected value of the winnings from a game will be [tex]2.96[/tex] .
What is Probability ?Probability is the ratio of the number of possible outcomes to the total number of outcomes.
we have,
Payout [tex](\$) = 0,\ \ \ 1,\ \ \ 2,\ \ \ 5,\ \ \ 10[/tex]
Probability [tex]=0.12,0.2,0.38,0.2,0.1[/tex]
So,
To find the expected value,
Now,
Multiply payout values with its probability and sum these values,
i.e.
Expected value [tex]= (0*0.12)+(1*0.2)+(2*0.38)+(5*0.2)+(10*0.1)[/tex]
[tex]=0+0.2+0.76+1+1[/tex]
Expected value [tex]=2.96[/tex]
Hence, we can say that the expected value of the winnings from a game will be [tex]2.96[/tex] .

1. You have a 16m by 24m rectangular area in your garden. You want to use it
to construct a swimming pool. The swimming pool will have a surrounding
foot path of 2m. If it costs $3 per square meters to tile the footpath, How
much will it cost to tile the entire footpath?
2m
2m
16 m
24 m

Answers
Answer:
Total cost of footpath = 528 m²
Step-by-step explanation:
Width of footpath is 2m.
Thus,
For longer footpath, there will be two sides. Thus; area = 2(24 + 2 + 2) × 2 = 112 m²
For shorter footpath, since the 2 longer sides have been taken care of, length remains 16m. Then area = 2(16 × 2) = 64 m²
Total area = 112 + 64 = 176 m²
cost to tile foot path is $3 per square metres.
Total cost of footpath = 176 × 3
Total cost of footpath = 528 m²

What is the perimeter of the rectangle?
Answers
Answer:
10 feet
Step-by-step explanation:
Perimeter of rectangle = 2l+2b
Area of the rectangle = l x b
Area of the rectangle = 4 square feet
possible factors of 4 = 2x2/4x1
So sides of the rectangle are 4 & 1 as 2&2 would make it a square
So perimeter= 2x4+2x1
= 8+2
