The answer is 28 in square
Answer:
Option C. 6 square units
Step-by-step explanation:
we know that
Heron's Formula is a method for calculating the area of a triangle when you know the lengths of all three sides.
Let
a,b,c be the lengths of the sides of a triangle.
The area is given by:

where
p is half the perimeter
p=
we have
Triangle ABC has vertices at A(-2,1), B(-2,-3), and C(1,-2)
the formula to calculate the distance between two points is equal to

step 1
Find the distance AB



step 2
Find the distance BC



step 3
Find the distance AC



step 4



Find the half perimeter p
p=
Find the area




The answer is C
You find this by dividing Y by X
Answer:
Step-by-step explanation:
Given the inequality
, we need to solve for "x".
We can subtract
to both sides:

(This step is shown in the exercise)
Now, we can add 10 to both sides:
(This step is not shown in the exercise)
And finally, divide both sides by -3:

(This is shown in the exercise)
Therefore, the missing step is:
Answer:
x=3
Step-by-step explanation:
1. cross multiply to get
5(4x+2)= 35(x-1)
2. distribute
20x+10=35x-35
3. combine like terms
45=15x
4. divide :)
3=x
