Step-by-step explanation:
the figure has 4 congruent sides and 4 right angles and is therefore a square, then
8x - 15 = 3x + 11 ( subtract 3x from both sides )
5x - 15 = 11 ( add 15 to both sides )
5x = 26 ( divide both sides by 5 )
x = 5.2
Answer:
It's a square
x = 26/5
Step-by-step explanation:
Well, since all the sides are equal (shown by the 3 lines in the sides) and all the angles are 90 degrees (show by the little squares in the corners), I believe the shape is a square.
Because the sides are equal, you would set up the equation by making the two expressions equal to each other:
3x + 11 = 8x - 15
The next step is to get the variable (x) on only one of the sides. You can do this by subtracting 3x from both sides or by subtracting 8x from both sides. I will subtract 3x here just so the new number can be positive, but either will work.
3x + 11 = 8x - 15
-3x -3x
0 + 11 = 5x - 15
Now, you isolate the x by adding 15 to both sides. Remember, whatever you do to one side, you must also do it to the other side of the equal sign.
11 = 5x - 15
+15 +15
26 = 5x
Lastly, get rid of the number in front of the x so that x is alone on a side of the equal sign. You do this by dividing both sides by 5.
x = 26/5
Now, you can either make this into a mixed number or a decimal or keep it how it is. I hope this helps :]

The model that can be used to determine the total amount of prize money based on the value of the first place prize is as follows;
Total amount of price money = 5x - 500
The prices are given to the best 5 acts. The first place wins the most money and each place after that wins $50 less than the previous place. The pattern follows a sequence.
What is a Sequence?Sequence is a list of things (usually numbers) that are in order. Therefore,

the first price = x
The common difference of the sequence would be - 50.
To create a model that can be used to determine the total amount of prize money based on the value of the first place prize can be done as follows;
x , x - 50, x - 100, x - 150, x - 200Therefore,
Total amount of price money = x + x - 50 + x - 100 + x - 150 + x - 200

School X and School Y play eachother in a competiton.
School X has eight more points than School Y
School X has three times as many points than School Y
How many points does each school have?
Answers
Answer:
school x = 12
school y = 4
Step-by-step explanation:
School X has eight more points than School Y.
School X has three times as many points as School Y .
Writing these statements in terms of equation
x = y + 8
x = 3 y
Substituting the value of x in y, we get
3 y = y + 8
Taking variable on left side of equation
3 y – y = 8 (subtract y from both sides)
2 y= 8 (divid 2 from both sides)
y = 4
then plug in y to the first equation
x= y + 8
x= 4 + 8
x= 12

w2 – 16w – 19 = 0
Answers
Answer:
Factoring w2-16w+19
The first term is, w2 its coefficient is 1 .
The middle term is, -16w its coefficient is -16 .
The last term, "the constant", is +19
Step-1 : Multiply the coefficient of the first term by the constant 1 • 19 = 19
Step-2 : Find two factors of 19 whose sum equals the coefficient of the middle term, which is -16 .
-19 + -1 = -20
-1 + -19 = -20
1 + 19 = 20
19 + 1 = 20
Observation : No two such factors can be found !!
Conclusion : Trinomial can not be factored
w2 - 16w + 19 = 0

Answers
Answer:
1st term = 7, 2nd term = 18, 3rd term = 39, 10th term = 403
Step-by-step explanation:
To find the 1st term substitute 1 for n in the equation:
4(1)² + 1 = (4 × 1) + 3 = 4 + 3 = 7
To find the 2nd term substitute 2 for n in the equation:
4(2)² + 3 = (4 × 4) + 3 = 16 + 3 = 18
To find the 3rd term substitute 3 for n in the equation:
4(3)² + 3 = (4 × 9) + 3 = 36 + 3 = 39
To find the 10th term substitute 10 for n in the equation:
4(10)² + 10 = (4 × 100) + 3 = 400 + 3 = 403

So these apple pies have a ratio of 15 apples to 3 pies. How many apples do you need for 12 pies?
Answers
Answer:
60
Step-by-step explanation:
since 15 apples makes 3 pies you divided 15 by 3 and get 5. 5 apples for one pie so that would be 5 x 12 = 60
Answer:
Since with 15 apples we are able to make 3 pies, this means that in each pie there are 5 apples (15apples divided by 3 pies = 5 apples.)
If there are 12 pies we simply have to multiply 12x5 which equals 60, this means that if we needed to make 12 pies we would need 60 apples.
15apples:3pies = 60apples:12pies

Step-by-step explanation:
the height from the 90° angle (which is y here) in a right-angled triangle is the square root of the Sergent lengths of the Hypotenuse.
y = sqrt(3×9) = 3×sqrt(3)
and x we get via Pythagoras :
x² = y² + 9² = 27 + 81 = 108
x = sqrt(108) = sqrt(36×3) = 6×sqrt(3)
so, A is correct.
