Answer:
-9
Step-by-step explanation:
b² - c²
= 4² - (-5)²
= 16 - 25
= -9
Answer:
36 × 18=648
Step-by-step explanation:
first one should do the area which results to 36 inches.
secondly do 3 × length of each side of the rectangle since scale factor is gotten by doing the recipricol of the scale factor given.
The cost of 1 vanilla ice cream and 1 strawberry ice cream should total to $31. Since you only bought one of each flavor, you simply have to add their unit prices.
Cost for 1 carton of strawberry ice cream + Cost for 1 carton of vanilla ice cream = Total Cost
Total Cost = s + v --> this is the general equation
Since s = 1.5 + v, the modified equation would be
Total Cost = 1.5 + v + v
Total Cost = 1.5 + 2v
Answer:
Step-by-step explanation:
m=x^3+y^2-6(x-y)-2021
distribute: 6x-6y
now you have m=x^3 + y^2 - 6x - 6y - 2021
Answer:
a) Suppose that F is ordered in ascending order: 
. Then, the complement of F can be written as
which is the union of a finite number of open intervals, then 
is an open set. Thus, F is a closed subset of the real numbers.
b) Take an arbitrary element of F, let us say 
. Now, choose a real number 
such that
there are not other element of F, because is less that the minimum distance between and its neighbors.
In case that 
we only consider 
, and if 
we only consider 
.
Then, all points of F are isolated.
