Answer:
Step-by-step explanation:
2x - 7 + 2x - 5 + 2x - 3 + 2x - 1 + 2x + 3 + 2x + 5 + 2x + 7 Combine like terms
16x / 8 = 48
2x = 48
x = 24
The range is defined as the largest number - the smallest number
The range is between 2x - 7 and 2x + 7
x = 24
The smallest number is 48 - 7 = 41
The largest number is 48 + 7 = 55
The range = 55 - 41 = 14
Why was the 2 in front of the x needed? It was to make sure that I could create an odd number.
Why did I subtract an odd number? That was to make sure that I could create odd numbers.
Why did I start with 2x - 7 and end up 8 terms later at 2x + 7?
So the numbers would cancel and I'd only be left with x's.

7 men can complete a work in 52 days. In how many days will 13 men
finish the same work?
Answer:
if 7 men complete the work in 52 days, it means a man will take (52×7=364)days to complete the same piece of work. therefore 13 men will take (364÷13)days which is equal to 28 days.
help me answer the last question
If the discriminant of an equation is positive, which of the following is true of the equation
A it has one complex solution
B it has one real solution
C it had two real solutions
D it has two complex solutions
Answer:
C it has two real solutions
Step-by-step explanation:
If the discriminant of a quadratic equation is positive, it means that the graph intersects the x-axis, and hence produces two real solutions.
If the discriminant is zero, then the graph is tangential to the x-axis, and there will be two real coincident solutions.
If the discriminant is negative, then there are two complex solutions.

What is the missing side length in the triangle below?
The cities of Raleigh, Durham, and Fuquay-Varina approximate a right triangle. The distance from Raleigh to Durham is 24 miles. The distance from Raleigh to Fuquay-Varina is 18 miles. What is the distance from Durham to Fuquay-Varina?
Answer:
The distance from Durham to Fuquay-Varina is 30 miles.
Step-by-step explanation:
Given that the cities of Raleigh, Durham, and Fuquay-Varina approximate a right triangle, and the distance from Raleigh to Durham is 24 miles, while the distance from Raleigh to Fuquay-Varina is 18 miles, to determine what is the distance from Durham to Fuquay-Varina, the following calculation must be performed, applying the Pythagorean theorem:
18 ^ 2 + 24 ^ 2 = X ^ 2
324 + 576 = X ^ 2
√ 900 = X
30 = X
Therefore, the distance from Durham to Fuquay-Varina is 30 miles.

Write an exponential function y=ab^x whose graph passes through the given points. (3, 56), (5, 224)
Answer:
y = 7*(2)^x
Step-by-step explanation:
We know that we have a function of the form:
y = a*b^x
Such that a and b are real numbers, and b also needs to be a positive number.
Such that this function passes through the points (3, 56) and (5, 224)
This means that:
56 = a*b^3
224 = a*b^5
So we have a system of two equations with two variables.
To solve this, we can take the quotient of the two equations (such that the second one is on the numerator) then we get:
(224/56) = (a*b^5)/(a*b^3)
4 = (a/a)*(b^5/b^3) = b^(5 - 3) = b^2
4 = b^2
Then we get:
√4 = b = 2
(because b needs to be positive we only care for the positive square root of 4)
The equation is something like:
y = a*(2)^x
Now we can use again the point (3, 56), so:
56 = a*(2)^3 = a*8
56 = a*8
56/8 = a = 7
Then the exponential equation is:
y = 7*(2)^x

What is the volume of this cylinder?
Answer:
The volume of this cylinder is 502.4 cubic inch
Step-by-step explanation:
For a given Cylinder
Radius (r) = 4 in.
Height (h) = 10 in.
Now,
Volume of Cylinder
V = πr²h
V = 3.14 × (4)² × 10
V = 3.14 × 16 × 10
V = 502.4 cubic inch
Thus, The volume of this cylinder is 502.4 cubic inch

Pascal wants to find the sum of the measures of the interior angles of a polygon that has n sides. How could he do this? Multiply 180 degrees by n. Multiply 180 degrees by (n + 2) Multiply 180 degrees by (n minus 2) Multiply 180 degrees by 2.
Answer:
Multiply 180 degrees by (n minus 2)
Step-by-step explanation:
Number of sides in the polygon = n
Polygons have sides 3, 4, 5, 6.....
Polygon with 3 sides is a triangle
Polygon with 4 sides is a quadrilateral
Sum of it's Interior angles = (n-2) × 180°
For a 3 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (3 - 2) × 180°
= 1 × 180°
= 180°
For a 4 sided polygon
Sum of it's Interior angles = (n-2) × 180°
= (4 - 2) × 180°
= 2 × 180°
= 360°
Answer:
Multiply 180 degrees by (n minus 2)

I need help with circle similarity / scale factor. can someone please help me out?
Answer:
A scale factor exists because any two circles are similar. You can use the radii to determine the scale factor.
Step-by-step explanation:
The ratio between the radii is 31 so the scale factor is 31=3. The circumference of the smaller circle is C=2π(1)=2π.

Answer:
1. a = 5, b = 8
2. d = 2
Step-by-step explanation:
1. The sum of two adjacent angles of a parallelogram is 180 degrees
Hence,
[tex]14a-5+115 = 180 \\14a = 180 -110\\a = 70/14\\a = 5[/tex]
Like wise
[tex]8b+1+115 = 180 \\8b = 180 -116\\8b = 64\\b = 8[/tex]
2.
The two intersecting diagonals cut each other into equal half
[tex]5d + 1 = 3d + 5\\2d = 4\\d = 2[/tex]
