Hello from MrBillDoesMath!
Answer:
3,8
Discussion:
Let "n" and "p" be the two positive integers. Then
n = p - 5 (*)
and
np = 24 (**)
Substituting (*) in (**) gives
np = 24 => as p = n+5
n(n+5) = 24 =>
n^2 + 5n - 24 = 0 => factor polynomial (n+8)(n-3)
So n = 3 or -8 but as n is positive, n = 3 Then p = n + 5 = 8
Check:
Is n (3) 5 less than p (8). Yes
Does np = 3 *8 24. Yes
Thank you,
MrB
The factorized form of the expression using the difference of two square is 2(x+3)(x-3)
Given the following function expressed as 2x^2 - 18
Factor out the GCF
2(x^2 - 9)
This can be written as
2(x^2 - 3^2)
According to the difference of two square, a^2 - b^2 = (a+b)(a-b)
Simplify
2(x^2-3^2) = 2(x+3)(x-3)
This given the factorized expression of 2x^2- 18

Hi Brainiac
2x² - 18
First you need to factor out the common term which is 2
2(x²-9)
Now factor x²-9
2(x+3)(x-3)
I hope that's help:0
3x+2y=14
2x-4y=4
6x+4y=28
2x-4y=4
8x = 32
x = 4
2y = 14 - 12 = 2
y = 1
(x , y) = (4 , 1)
Question:How can check your solution by writing the system as a matrix equation and using the inverse matrix?.
To check the solution, represent the system of equations as a matrix equation, find the inverse of the coefficient matrix, and multiply both sides of the equation by the inverse.
To check the solution by writing the system as a matrix equation and using the inverse matrix, we need to represent the system of equations as a matrix equation. Let's consider the given system of equations:
3x + 2y = 14
2x - 4y = 4
To do this, we can write the coefficients and constants of the system of equations as matrices:
[3 2] [x] = [14]
[2 -4] [y] = [4]
Now, we can write the system of equations as a matrix equation: AX = B, where A is the coefficient matrix, X is the variable matrix, and B is the constant matrix.
Next, we need to find the inverse of matrix A. If the inverse exists, we can multiply both sides of the matrix equation by the inverse of A to find the solution for X.
If we find the inverse of A and multiply both sides of the equation by the inverse, we get:
X = A-1B
Substituting the values of A-1 and B, we can find X, which represents the solution to the system of equations. Therefore, we can check our solution by writing the system as a matrix equation and using the inverse matrix.

100 = 0.20 × k
p = 0.20 × 100 × k
p = 0.20k + 100
0.20k = 100 + p
