Answer:
a) because of the distributive property when you distribute you get 2x+8=2x+8
b) because when you distribute, you get 3x+7=3x+21 which is not equal so no value of x will work
Answer:
a) 2x + 8 = 2(x + 4) has infinite solutions because it simplifies down to x = x. Here is the work where this equation is solved.
2x + 8 = 2(x + 4)
2x + 8 = 2(x) + 2(4)
2x + 8 = 2x +8
2x + 8 - 8 = 2x + 8 -8
2x = 2x
2x/2 = 2x/2
x = x
So, because the equation ends in x = x, you can substitute any value for x and the equation will remain true.
----------------------------------------------------------------------------------------------------------------
b) 3x + 7 = 3(x + 7) has no solutions because it simplifies down to an untrue statement. The equation is simplified below.
3x + 7 = 3(x + 7)
3x + 7 = 3(x) + 3(7)
3x + 7 = 3x + 21
3x + 7 - 7 = 3x + 21 - 7
3x = 3x + 14
3x/3 = 3x/3 +14
x = x + 14
However, this is false. x cannot be equal to itself plus 14.
x ≠ x + 14
The simplification of this equation is untrue, so there is no solution to it.

Hue is arranging chairs. She can form 6 rows of a given length with 1 chair left over, or 9 rows of that same length if she gets 11 more chairs. Complete the equation and solve it to find how many chairs are in that row length. In your equation, use the variable x to represent the number of chairs in each row.
Answer:
There are 7 chairs in each row length.
Step-by-step explanation:
Let number of chairs in 1 row be 'x'.
Let total number of chairs be 'y'.
Given:
Hue can form 6 rows of a given length with 3 chairs left over.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 6 plus number of chairs which is left which is 3.
Framing in equation form we get.
Also Given:
Hue can form 8 rows of that same length if she gets 11 more chairs.
It means that Total number of chairs is equal to chairs in 1 rows multiplied by number of rows which is 8 minus number of chairs which is required more which is 11.
Framing in equation form we get.
From equation 1 and equation 2 we can say that L.H.S is same.
So according to law of transitivity we get;
Combining like terms we get;
Using Subtraction and Addition property we get;
Now Using Division Property we will divide both side by 2.
Hence there are 7 chairs in each row length.

Christopher sold his dinette set for $245 through an online site, which charged him 9% of the selling price as commission. what is the commission?
Answer:
$22.05
Step-by-step explanation:
If a product has a sales commission, then one must divide the commission percent by (100) to convert the percent to a decimal. Then multiply the result by the price of the product to find the amount of money that will be given as a commission.
Applying this knowledge to the given problem, one must divide (9%) by (100) to convert to decimal form,
9% / 100 = 0.09
Now multiply the result by the price of the product (245) to find the amount given away in commission,
0.09 * 245 = 22.05

The probability of getting outcomes including 2 true and 2 false answers is 3/8.
The given sample space is {TTTT, TTTF, TTFT, TTFF, TFTT, TFTF, TFFT, TFFF, FTTT, FTTF, FTFT, FTFF, FFTT, FFTF, FFFT, FFFF}
We need to find how many outcomes include 2 true and 2 false answers.
What is the formula to find the probability of an event?The formula to find the probability of an event is P(E)=Number of favourable outcomes/Total number of outcomes.
Now, the number of favourable outcomes=6 and = the total number of outcomes=16.
So, P(E)=6/16=3/8
Therefore, the probability of getting outcomes including 2 true and 2 false answers is 3/8.

A triangle has sides with lengths of 28 feet, 96 feet, and 100 feet. Is it a right triangle?
Answer:
Yes, itis a right triangle (Brainliest pls :3)
Step-by-step explanation:
Using the hypotenuse formula you can calculate it
Yes it is a right triangle.
Given that,
A triangle has sides with lengths of 28 feet, 96 feet, and 100 feet.
We have to determine,
Is it a right triangle.
According to the question,
To determine if a triangle contains a right angle using Pythagoras' theorem.
If the squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.
Therefore,
By Pythagoras theorem,
[tex](Hypotenuse)^{2} = \ (Base)^{2} +\ ( perpendicular)^{2}\\[/tex]
The triangle has sides with lengths of 28 feet, 96 feet, and 100 feet.
Then,
The squares of the two shorter sides add up to the square of the hypotenuse, the triangle contains a right angle.
[tex]=(28)^{2} + (96)^2 = (100)^2\\\\= 784 + 9216 = 10000\\\\10000 = 10000[/tex]
It is a right angle triangle.
Hence, Yes it is a right triangle.
