n!-(n-1)!=16(n-2)! by factorizing it by n! and dividing it by n! we get n is equal to 2 .
what is polynomial ?The intersection point in mathematics is the location on the y-axis where the slope of the line passes. a point where a line or curve's y-axis crosses it. This is demonstrated using the equation for the straight line, Y = mx+c, where m denotes the slope and c the y-intercept. The equation's intercept form highlights the line's slope (m) and y-intercept (b). The slope is m and the y-intercept is b when an equation has the intercept form (y=mx+b). It is also possible to rewrite some equations so that they resemble slope intercepts. For example, the slope and y-intercept are both modified to 1 if y=x is rewritten as y=1x+0.
given
n! + (n+1)! = (n+2)!
Let us rewrite:
n!+ (n+1)n! = (n+2)(n+1)n!
Factorize n!
n!(1+n+1) = (n+2)(n+1)n!
Divide by n!
==> n+2 = (n+2)(n+1)
No divide by (n+2)
==> 1= n+1
==> n = 0
to verify substitute with n=0
==> 0! + 1! = 2!
==> 1+1 = 2
==> 2=2
n!-(n-1)!=16(n-2)! by factorizing it by n! and dividing it by n! we get n is equal to 2 .

What is the value of x to the nearest whole number? 18 20 86 94
Answer:
18
Step-by-step explanation:
From the above question,
We have the Algebraic expression
(5x - 4)° + 94° = 180°
5x - 4° + 94° = 180°
5x + 90° = 180°
5x = 180° - 90°
5x = 90°
x = 90°/5

What the surface area of a rotating prism?To find the surface area of any kind of prism we use the general formula. The total surface area of a prism is the sum of lateral surface area and area of two flat bases.
The total surface area of a Prism = (2 × Base Area) + (Base perimeter × Length).
Here, area of base is Area=2(Base×Height)
= 2(6×4)
= 12 square millimeters
Now, Base perimeter × Length= (5+5+6)×7
= 16×7
= 112 square millimeters
Total area = 12+112
= 124 square millimeters
Therefore, the total surface area is 124 square millimeters.

After dinner 1-3 of the corn bread is left suppose 2 friends want to share it equally what fraction names how much of the whole pan of corn bread each f riend will get
Answer:
Each friend will get [tex]\frac{1}{18}[/tex] of whole pan of corn bread
Step-by-step explanation:
As given,
Corn bread left = [tex]\frac{1}{3}[/tex]
Total number of friends = 2
So the left bread will divide into 2 parts
So, each person will get = [tex]\frac{1}{2}[/tex] ( [tex]\frac{1}{3}[/tex] ) = [tex]\frac{1}{6}[/tex] of the left bread
Now,
Left bread = [tex]\frac{1}{3}[/tex] of whole bread
And
Each person get = [tex]\frac{1}{6}[/tex] of the left bread
= [tex]\frac{1}{6}[/tex] ×[tex]\frac{1}{3}[/tex] of whole bread
= [tex]\frac{1}{18}[/tex]of whole bread
∴ we get
Each friend will get [tex]\frac{1}{18}[/tex] of whole pan of corn bread

What is the slope of the line shown?
A. slope = 3
B. slope = 1/2
C. slope = 2
D. slope = -3
Answer:
The answer is B - 1/2.
Step-by-step explanation:
Rise over run tells you the slope. You take two points (in this it's (0,-3) and (6,0)) and you see how many units it takes to be on the same y line as the other point. Then you do the same for the x line. You divide the rise (y line) by the run (x line) and that's your slope.
in integers how to know if minus (-) 1 upon 2 is greater or minus (-) 1 is greater???
Answer:
1/2 is 0.5 so -1/2=-0.5
-0.5 is greater than -1
use a number line
Step-by-step explanation:
By looking at the number line we can easily tell which integers are greater (larger) than a certain number and which are less (smaller) than the number. When two numbers are located on a number line, the number to the right is larger than the number to the left. –1 is less than –1/2 because it is to the left of –1/2.

1- The area of a parallelogram is 507 cm2. Its height is six times its base. Find the height and base.
Answer:
507=b x (3 x b)
507=b x 3b
507=3b^2
b^2=507/3
b^2=169
b=13
h=3 x b
h=3 x 13
h=39
Step-by-step explanation:
The height and base of the parallelogram is b = 13 cm and h = 78 cm
What is a Parallelogram?A parallelogram is a simple quadrilateral with two pairs of parallel sides. The opposite or facing sides of a parallelogram are of equal length and the opposite angles of a parallelogram are of equal measure
The sum of angles of a parallelogram is 360°
The four types are parallelograms, squares, rectangles, and rhombuses
Properties of Parallelogram
Opposite sides are parallel
Opposite sides are congruent
Opposite angles are congruent.
Same-Side interior angles (consecutive angles) are supplementary
Each diagonal of a parallelogram separates it into two congruent triangles
The diagonals of a parallelogram bisect each other
Given data ,
Let the area of the parallelogram be represented as A
Now , the value of A = b x h
where the base of the parallelogram is b
The height of the parallelogram is h
So , 507 = b x h
And , height is three times its base
So , h = ( b x 3 )
On simplifying , we get
507 = b ( b x 3 )
507 = 3b²
Divide by 3 on both sides , we get
b² = 169
Taking square roots on both sides , we get
b = 13 cm
So , the height of the parallelogram is h = 78 cm
Hence , the parallelogram is solved
