Answer:
(p - 5)(p + 1)
Step-by-step explanation:
Given
p² - 4p - 5
Consider the factors of the constant term (- 5) which sum to give the coefficient of the x- term (- 4)
The factors are - 5 and + 1 , since
- 5 × + 1 = - 5 and - 5 + 1 = - 4, then
p² - 4p - 5 = (p - 5)(p + 1) ← in factored form
The standard form of a trinomial is
ax² + bx + c ( a ≠ 0 )
p² - 4p - 5 ← is in standard form
with a = 1, b = - 4 and c = - 5
An equation is given.

26
2x=26
Which calculation would need to be done to solve the equation?
A
divide both sides by 2626
B
multiply both sides by 2626
C
divide both sides by 22
D
multiply both sides by 2
D because 2 has a x next to it so you divide by 2 on both sides
Which two values of x are roots of the polynomial below? (select all that apply
3x^2-3x+1
The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6 thus options (A) and (B) are correct.
What is a quadratic equation?An algebraic equation of the second degree in x is a quadratic equation. The quadratic equation is written as ax2 + bx + c = 0, where x is the variable, and a must not be zero.
As per the given equation,
3x² - 3x + 1
To find the roots of the above quadratic equation,
3x² - 3x + 1 = 0
x = [-(-3) ± √((-3)² - 4×3×1)]/(2×3)
x = [3 ± √(-3)]/6
x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6
Hence "The roots of the given quadratic equation 3x² - 3x + 1 are x = [3 + √(-3)]/6 and x = [3 - √(-3)]/6".

A basket ball player attempts 15 baskets in a game . He makes 9 of the attemps what is the ratio
Answer:
9:15 or 3:5
Step-by-step explanation:
A ratio can compare a part of a whole to a whole.
In this case, our whole is the total number of shots attempted: 15.
The basketball player successfully made 9 of the attempts. 9 is our other number in this ratio.
Put these values in a ration.
part:whole
9:15
Notice that 9 and 15 can be simplified by dividing both numbers by 3.
3:5
This is your simplified ratio.

Mars has m moons. The number of moons of Pluto is one more than twice the number of moons of Mars. The number of moons of Neptune is one less than 3 times the number of moons of Pluto. Write and interpret a simplified expression that represents the number of moons of Neptune (I’m just asking to answer because I didn’t see any right ones when I was scrolling through them)
Answer:
neptune = 6m+2
Step-by-step explanation:
mars has 'm' moons
pluto has one more than twice that of mars, = 2m+1
neptune is one less than thrice of pluto
= 3(2m+1) -1
= 6m+3 -1
= 6m+2

Answer: 1.5 x 10^5
Step-by-step explanation:
The first step is to re-arrange the factors like this :
5 x 3 x 10^2 x 10^2
Since
5 x 3 = 15
and the index law
10^a x 10^b = 10^a + ^b
gives us
10^2 x 10^2 = 10^2 + ^2 = 10^4
then we can rewrite the product like this :
5 x 3 x 10^2 x 10^2 = 15 x 10^4
Finally, we need to convert this into scientific notation :
15 x 10^4 = 1.5 x 10^5
So the final answer is
1.5 x 10^5

What is the slope of the equation: y = - 5x -6
What is the y-intercept of the equation: y = 2x
Answer:
Step-by-step explanation:
y = mx +b
Here, m is slope and b is y-intercept
1) y = -5x - 6
Slope = -5
y-intercept = -6
2) y = 2x
Slope = 2
y-intercept = 0

How many kilograms of 30% salt solution by mass and 40% salt solution by mass
should be mixed to form 200 kg of 37% salt solution by mass?
Answer:
60 kilograms of the 30% solution
140 kilograms of the 40% solution
Step-by-step explanation:
Let x = the no. of kilos containing 30% salt (solution 1)
and 200 - x = the no. of kilos containging 40% salt solution 2)
.30x = amount of salt in solution 1
.40(200 - x) = amount of salt in solution 2
.37(200) = amount of salt in the final mixture
salt in solution 1 + salt in solution 2 = salt in final mix.
.30x + .40(200 - x) = .37(200)
Let's multiply thru the equation by 100 to remove the decimal fractions
30x + 40(200 - x) = 37(200)
30x + 8000 - 40x = 7400
-10x = -600
x = 60 kilograms of the 30% solution
200 - 60 = 140 kilograms of the 40% solution

From which set of dimensions could a triangle be constructed?
side length of 7
side length of 8
side length of 15
side length of 8
side length of 5
side length of 14
side length of 6
side length of 3
side length of 10
side length of 2
side length of 6
side length of 7
Answer:
side length of 2
side length of 6
side length of 7
Step-by-step explanation:
So remember the two shorter lengths added together have to be greater than the longest side length
For the first answer choice we add 7 and 8
7+8=15
The two shorter sides added are not greater then the longest side so that is not the answer
For the second answer choice we add
8 and 5
8+5=13
13 is not greater than 14 so this is not the answer choice either
For the third one we add 6 and 3
6+3=9 which is not greater than 10 so this is not the answer
For the last one we add 2 and 6
2+6=8 which is greater than 7 so this one is the answer

This is a similar triangle. Please find the missing length. (?)
Answer:
RQ = 10
Step-by-step explanation:
When two triangles are similar, the ratio of their corresponding sides are equal;
Thus, we have it that;
QP/RQ = BC/AB
12/RQ = 36/30
RQ = 12 * 30/36 = 10
