Answer:
(x - 24)(x + 3)
Step-by-step explanation:
Given
x² - 21x - 72
Consider the factors of the constant term (- 72) which sum to give the coefficient of the x- term (- 21)
The factors are - 24 and + 3, since
- 24 × + 3 = - 72 and - 24 + 3 = - 21 , then
x² - 21x - 72 = (x - 24)(x + 3) ← in factored form

20%= $9.98
49.90+9.98 =59.80
(59.80)(6%)
6%= $3.58

Leah's rectangular driveway is 48 feet long and 14 feet wide. With sidewalk chalk, Leah drew a straight diagonal line on her driveway from one corner to the opposite corner.
How long is the diagonal line Leah drew?
25 feet
46 feet
50 feet
62 feet
[tex]48^2+14^2=x^2\\x^2=2500\\x=50[/tex]
The length of the diagonal drawn by Leah will be 50 feets
Given the Parameters :
Length = 48 feet Width = 14 feetsThe length of the diagonal is the value of the hypotenus in a right angles triangle :
Let the length of the diagonal = d
d = √(length)² + (width)²
d = √48² + 16²
d = √2304 + 256
d = √2560
d = 50.5961 feets
Therefore, the closest value for the length of the diagonal in the options given is 50 feets

Answer:

Step-by-step explanation:
The field has the shape of a trapezoid. Its area can be found using the formula for the area of a trapezoid:
A = (1/2)(b1 +b2)h
A = (1/2)(399 +594)(506) = 251,229 . . . . . . acres
__
At 38909 plants per acre, the number of plants that should be planted for maximum yield is ...
(251,229 ac)(38,909 plants/ac) = 9,775,069,161 plants
_____
Comment on units
The problem statement tells us "each unit of coordinate plane represents one acre." An acre is a unit of area, so we have to assume this means that each square unit represents one acre. That means each unit on each axis is about 208.71 feet, the dimension that would have to be squared to get an area of one acre--43,560 square feet.
If t is a number between 6 and 9, t+5 is between what two numbers?
Answer:
11 and 14
Step-by-step explanation:
t can be 7 or 8
7+5=12
8+5=13
12 and 13 are between 11 and 14
The number t + 5 is in between 11 and 14.
What is an inequality?"It is a mathematical statement of an order relationship (greater than, greater than or equal to, less than, or less than or equal to) between two numbers or mathematical expressions."
What is addition property of inequality?" Let x, y, and z be real numbers.
If x > y, then x + z > y + z."
For given question,
t is a number between 6 and 9.
So, we have an inequality.
⇒ 6 < t < 9
By addition property of inequality,
⇒ 6 + 5 < t + 5 < 9 + 5
⇒ 11 < t + 5 < 14
Therefore, the number t + 5 is in between 11 and 14.

what is the volume of the rectangular prism
It is all the numbers multiplied together. 135
Answer:
[tex]\Huge\boxed{D.135 cm^3}[/tex]
Step-by-step explanation:
Hello There!
We can find the volume of the figure by using the formula for volume of a rectangular prism
[tex]V=lwh[/tex]
where l = length, w = width and h = height
we are given all of the dimensions so all we have to do is plug in the values
so
V = 3 x 9 x 5
3x9=27
27x5=135
so the volume of the rectangular prism is 135 cm³
Find the value of x. Please

Answer:
The equations that represent an exponential decay are;
A; [y = (0.1)ˣ]
B; [y = 2·(0.3)ˣ]
Step-by-step explanation:
An exponential decay is given by the following formula;
y = a·bˣ
Where;
b < 1
For option A, we have; [y = (0.1)ˣ]
Here; a = 1, b = 0.1 < 1, therefore, the function represents an exponential decay
For option B, we have; [y = 2·(0.3)ˣ]
Here; a = 2, b = 0.3 < 1, therefore, the function represents an exponential decay
For option C, we have; [tex]\left[y = \left(\dfrac{4}{3} \right)^x\right][/tex]
Here; a = 1, b = [tex]\dfrac{4}{3} \right) > 1[/tex], therefore, the function does not represent an exponential decay
For option D, we have; [tex]\left[y = \left(\dfrac{7}{5} \right)^x\right][/tex]
Here; a = 1, b = [tex]\dfrac{7}{5} \right) > 1[/tex], therefore, the function does not represent an exponential decay
How do I factor the polynomial -7y+y^2-30? I can do it in standard form but now im confused. Please help.

hope this helps
Answer:
Step-by-step explanation:
-7y+y^2-30 is presented legally, but not logically I will re-write it better
just re-write in standard form
