a number from 1 to 10. the product of 3 less than this number and 2 more than this number is equal to 14. which equation could be used to solve for kevin's number, x?
The number is 5, the equation used is [tex]x^{2}[/tex] - x - 20 = 0
Let x be the number which is between 1 to 10.
From the question we get to know the equation:
(x-3)(x +2) = 14
x(x+2) -3(x+2) =14
[tex]x^{2}[/tex] +2x -3x - 6 =14
[tex]x^{2}[/tex] - x - 6 =14
[tex]x^{2}[/tex] - x - 20 = 0
This is the equation used to solve for Kevin's number.
Now we have to find the value of x.
[tex]x^{2}[/tex] - 5x + 4x -20=0
x(x-5) + 4(x-5) = 0
(x-5)(x+4) = 0
x = 5, -4
Hence we get two values of x which is 5, -4. But we have to find the number between 1 and 10.
Hence from the value of 5 and -4 , the number is 5 which is between 1 and 10 as -4 is not in the range of 1 to 10.

Point Q is on line segment PR. Given PQ=x,QR=6, and PR =2x-10, determine the numberical length of PR
When Point Q is on line segment PR, if PQ=x,QR=6, and PR =2x-10, then the length of PR is 18 units
Given,
That point Q is on line segment PR
The length of PQ = x
The length of QR = 6
The length of PR = 2x-10
We know,
Point Q is on line segment PR
So, the length of the PR = Length of PQ + Length of QR
Substitute the values in the equation
2x-10 = x+6
2x-x=6+10
x=14
Substitute the value of x in the equation of the length of line PR
PR= 2x-10
=2×14-10
=28-10
=18 units
Hence, when Point Q is on line segment PR, if PQ=x,QR=6, and PR =2x-10, then the length of PR is 18 units

If a circular railroad crossing sign has an area of 254.34 in ^2, what is the diameter of the sign?
The diameter is 18 inches.
How to calculate the diameter?It should be noted that the area of a circle is represented by πr². This will be:
πr² = 254.34
(3.14 × r²) = 254.34
3.14r² = 254.34
r² = 254.34/3.14
r² = 81
r = ✓81
r = 9
Therefore the diameter will be:

Distance from Loretta's house to Jamal's house = 31 miles.
Jamal's house is in between Loretta's house and the park.
Let 'x' be the distance from Jamal's house to the park.
So the distance between Loretta's house and the park is more than the distance from Jamal's house and the park.
Also the distance from Loretta's house to the park is the sum of the distance from Loretta's house to Jamal's house and the distance from Jamal's house to the park.

10/3 ( width)
Step-by-step explanation:
the length of a rectangle is twice the width if the perimeter is 20 cm find the width
we can solve with an equation
(2x + x) * 2 = 20
3x * 2 = 20
6x = 20
x = 20 : 6
x = 10/3 ( width)

he brazilian free-tailed bat can travel 99 miles per hour. after sunset, a colony of bats emerges from a cave and spreads out in a circular pattern. how long before these bats cover an area of 80,000 square miles? use π
The bat colony will cover an area of 80,000 square miles in 1.612 hours.
What is defined as the circle?A circle is the collection of all the points together in plane that are equally distant from the a given point known as the circle's center. A circle is represented by the symbol. A radius of a circle is a line segment that connects the center of a circle toward any point on the circle.
Now, as per the given question;
The area covered (A) by the colony, evaluated in square miles, is depicted by the mentioned geometrical formula as the bat colony emerges from a cave & spreads out in a circular pattern:
A = π R²
R = the bat's distance from the cave, calculated in miles.
Furthermore, each bat moves at a constant speed, and distance is depicted by the following kinematic formula:
R = r₀ + rΔt
r₀ = The bat's initial distance from the cave, estimated in miles.
r = Bat speed, estimated in miles per hour.
Δt = Time, expressed in hours.
Substitute the value of R in the formula of area.
A = π (r₀ + rΔt)²
(r₀ + rΔt)² = A/ π
(r₀ + rΔt) = √(A/ π)
rΔt = √(A/ π) - r₀
Δt = (√(A/ π) - r₀)/r
r = 99 miles per hour
The distance between the bat and the cave has now been substituted, and time has been cleared:
A = area of 80,000 square miles
π = 3.14
r₀ = 0 miles per hour
Substituting all the values in the A we calculate the time.
Δt = (√( 80,000/3.14) - 0)/99
On solving;
Δt = 1.612 (approx)
Thus, It will take 1.612 hours for the bat colony to cover an area of 80,000 square miles.
