Answer:
12 and 10 and
-12 and - 10
Step-by-step explanation:
Givens
Larger number = x
Smaller number = x - 2
Equation
x*(x - 2) = 120
Solution
Remove the brackets
x^2 - 2x = 120
Subtract 120 from both sides
x^2 - 2x - 120 = 0 Factor
(x - 12)(x + 10) = 0
x - 12 = 0
x - 12 + 12 = 12
the other number is 2 less than this one or x = 10
=================
x + 10 = 0
x = - 10
The number that is 2 less than this one is
x = -10 -2
x = -12

a
Step-by-step explanation:
Answer:
0.5
Step-by-step explanation:
Total space in the parking lot = 10
number of cars parked = p
number of empty parking spaces = e
There are the same number of cars parked in the parking lot as there are empty parking spaces.
This means,
Number of parked cars = number of empty parking spaces
p = e
If the number of parked cars and number of empty parking spaces = 10
p + e = 10
If p = 5
Then,
p + e = 10
5 + 5 = 10
Write a decimal to show the part of the parking lot that has empty parking spaces.
Empty parking space/total parking space
= 5/10
= 1/2
= 0.5
part of the parking lot that has empty parking spaces = 0.5
Let's call this blank X
x÷4=9
x=4×9
x=36
hope that helped
