Answer:
(-4, -2)
Step-by-step explanation:
To find if a point is a solution (or verifies) an inequation (or an equation), you simply have to enter the given values in it and see if it's true.
Let's try with all the 4 given choices:
(-4, -2)
y + x < -5
-4 - 2 < -5
-6 < -5 TRUE
(-3, -2)
y + x < -5
-3 - 2 < -5
-5 < -5 FALSE
(-2, -3)
-2 - 3 < -5
-5 < -5 FALSE
(-1, -3)
-1 - 3 < -5
-4 < -5 FALSE
Set the length of the base as x, the two equal sides are then 4x each, so the perimeter is x+4x+4x=9x
Is this what you are looking for? I hope this helps!
we must do the following:
0
1
2
3
4
5
6
7
8

select the major, the minor and the half and add, like this:

therefore:

also:

the groups are:
