Answer:
(x - 5)(x + 3)
Step-by-step explanation:
to solve x² - 2x = 15, we need to get all the terms on one side so we can solve the quadratic equation using factoring. to do this, we subtract 15 from both sides
x² - 2x = 15
- 15 -15
x² - 2x - 15 = 0
now we can factor. we need 2 numbers that when multiplied together give us -15, and when those 2 numbers are added together we get -2
because we have a -15, we can assume that one number must be negative and the other positive, as a negative times a postive is a negative.
we can use 3 and -5 as factors and test it out. we put x in front because we have an x²
(x - 5)(x + 3) < we can FOIL to check to see if this is correct. its not mandatory to check but when you arent sure of the answer you can FOIL it out
FOIL stands for: First, Outside, Inside, and Last terms
F: (x - 5)(x + 3) = x²
O: (x - 5)(x + 3) = -3x
I: (x - 5)(x + 3) = 5x
L: (x - 5)(x + 3) = -15
x² + 3x - 5x - 15 < subtract 3x from 5x
x² - 2x - 15
this checks out, so our answer is (x - 5)(x + 3)
A trapezoid has two parallel sides, but the top one is shorter than the bottom one
80.6 / 6.2 = 13
I think the base is 13 meters.
Formula is area = b times height

Difficult to sell
Explanation
There are many factors that limit the mobility and they are contributed by factors such as disease and accidental factors and there are many persons with disabilities
Many changes must be done with the layout of the home so if a house is designed with limited mobility it is very difficult to sell. Each and every different mobility homes have certain specifications and different accommodations.
The yards must be designed with mobility issues and they must create a stable and a wide pathway and these are much essential for wheel chair access
