You use distributive property. So (5 x 2)-(5 x x)= 10 - 5x.
<h3>Answers:</h3><h3>First box = 57.14</h3><h3>Second box = 80</h3>
=============================================
Explanation:
If you save 65%, then you pay the remaining 35%
0.35x is the final price when x is the original price
0.35x = 20 solves to x = 57.14 approximately after dividing both sides by 0.35
57.14 goes in the first box
--------------
This must mean 80 goes in the other box.
Here's the steps on how to get 80
If you save 75% then you pay the remaining 25%
0.25x = 20
x = 20/0.25
x = 80
80 goes in the second box

Answer:
A. x
C. x – 5
D. x + 2
Step-by-step explanation:
From the question above, we are asked to find the factors of an algebraic expression that is given as:
x³ - 3x² - 10x
We would use the step of factorisation
Step 1
x(x² - 3x- 10)
The first factor of the algebraic expression has been obtained = x
Step 2
We factorise x² - 3x - 10
x² +2x - 5x - 10
(x²+2x) - (5x - 10)
x(x + 2) -5(x + 2)
(x + 2)(x - 5)
Step 3
x³ - 3x² - 10x
x(x² - 3x- 10)
(x)(x + 2)(x - 5)
Therefore, the factors of the algebraic expression are:
(x), (x + 2), (x - 5)
