4n^2-15n-25 factor trinomials pls help me on this i would love if you would put the steps too thank you
---Multiply a x c
Quadratic Form: ax^2 + bx + c
4 x -25 = -100
---Find a factor pair of -100 that adds up to -15
-20 x 5 = - 100
-20 + 5 = -15
---Separate the b term into your two factors
4n^2 + 5n - 20n - 25
This can take some trial and error (though there are only two options) because when you factor, you want the inside of the parentheses to be the same. If you look at the next step, (4n + 5) appears twice.
---Factor each binomial
n(4n + 5) - 5 (4n + 5)
---Rewrite
(n - 5)(4n + 5)
What you're really doing here is factoring out the (4n + 5), which leaves you with the terms that you factored out in the previous step. You then combine these terms into one set of parenthesis.
Answer: (n - 5)(4n + 5)
Hope this helps!

Answer:
Step-by-step explanation:
I'm not oversimplifying this answer.
If 1 inch is .25 miles then all you have to do is multiply .25 miles by 5 inches and u get 1.25 miles.
[tex]\begin{array}{ccll} \stackrel{in}{model}&\stackrel{mi}{actual}\\ \cline{1-2} 1 & 0.25\\ 5& x \end{array} \implies \cfrac{1}{5}=\cfrac{0.25}{x}\implies x=(5)(0.25)\implies x=1.25[/tex]

Which linear inequality is represented by the graph?
Answer:
y≤2/3x+1/5
or the very first one
Step-by-step explanation:
You flip a coin and use a random numer generator to generate a number 1 to 8. What is the probability that the coin shows tails and is the number 2
probability of getting a tail , PA = 1/2
probability of gettin a number 2 , PB = 1/8
now ,
the probability to get tail and 2 = PA x PB = 1/2 x 1/8 = 1/16.
hence it's the answer.

Solve this system of linear equations. Separate
the x- and y-values with a comma.
15x = -42 - 19y

3x+19y+54=0--(2)Subtract both

3(1)+19y+54=019y+57=0y=-3So
(x,y)=(1,-3)Answer:
1, -3
Step-by-step explanation:
QuestionSolve the system of linear equations:
15x = -42 - 19y3x = -54 - 19y-------------------------------------------------------------------------------------
SolutionSubtract the equations to eliminate y:
15x = -42 - 19y
- 3x = -54 - 19y
----------------------
12x = 12
⇒ x = 12 ÷ 12
⇒ x = 1
Now substitute the found value of x into one of the equations and solve for y:
⇒ 15x = -42 - 19y
⇒ 15(1) = -42 - 19y
⇒ 15 = -42 - 19y
⇒ 19y = -42 - 15
⇒ 19y = -57
⇒ y = -57 ÷ 19
⇒ y = -3
Therefore, x = 1 and y = -3

the area of the triangle below is 29.25 square centimeters the height is 6.5. what is the length of the base?
Answer: 9
Step-by-step explanation:
½bh = 29.25
½ × 6.5 × b = 29.25
B= 29.25/ 3.25
The length of the base of the triangle is 9 centimeters.
What is the base length of the triangle?The area of a triangle is simply expressed as half base multiplied by height.
Area A = 1/2 × base length × height
Given the dimensions of the triangle:
Area A = 29.25 square centimeters
Height = 6.5 centimeters
Base length =?
To find the height of the triangle, plug the given values into the above formula and solve for h:
Area A = 1/2 × base length × height
29.25 = 1/2 × base length × 6.5
29.25 = base length × 3.25
Base length = 29.25 / 3.25
Base length = 9 cm.
Therefore, the base length measures 9 centimeters.

the perimeter of an equilateral triangle is 6cm find its area
Answer:
√3 cm
or
1.73 cm to the nearest hundredth.
Step-by-step explanation:
Each side must be 2 cm long
Using Heron's formula
Area = √(s(s-a)(s-b)(s-c) where s = semi-perimeter, a , b and c are the 3 side lengths.
So here s = 6/2 = 3 and all the sides = 2 so
Area = √(3(3-2)^3
= √3 cm.

A doctor observes a graph that shows the electrical activity (in volts) of the heart of a patient over a period of time (in seconds). Each spike corresponds to one heart beat. The doctor needs to calculate the heart rate of the patient in beats per minute.
What is the heart rate of this patient?
To calculate a patient's heart rate, the doctor must take into account a segment of time, such as a minute, and count the number of times the heart beats in that segment.
What is heart rate?Heart rate is a term that refers to the number of heart contractions or beats per unit of time.
Heart rate is usually measured at various points, but most commonly it is measured at the wrist, neck, or chest.
According to the above, the most common way for the doctor to establish the patient's heart rate is to count the heart beats in a segment of time such as one minute.

How to find the density and volume?She is serving hot coffee and cold coffee in two rectangular-shaped tanks, each with dimensions width of 8.75 inches, a length of 8.75 inches, and a height of 23 inches.
The hot coffee has a density of 5.8 oz/in³ and the cold coffee has a density of 3.5 oz/ in³.
Then the volume of the coffee in each tank will be
We know that the dimension of both tanks is equal. Then the volume will remains equal.
Volume = L × B × H
Volume = 8.75 × 8.75 × 23
Volume = 1760.9375 ≅ 1760.94 in³
Then the mass of the coffee in each the tank will be
The mass of hot coffee will be
Mass = Density × Volume
Mass = 5.8 × 1760.94
Mass = 10213.45 oz
The mass of cold coffee will be
Mass = Density × Volume
Mass = 3.5 × 1760.94
Mass = 6163.29 oz
