Answer:
The formula that represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A) is .
Step-by-step explanation:
We are given the area of an Equilateral triangle which is A = . And we have to represent the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
So, the area of an equilateral triangle =
where, s = side of an equilateral triangle
A =
Cross multiplying the fractions we get;
Now. moving to the right side of the equation;
Taking square root both sides we get;
Hence, this formula represents the length of an equilateral triangle’s side (s) in terms of the triangle's area (A).
The point-slope form:
We have the point (-1, 7) and the slope m = 2. Substitute:
Answer:
Multiplying the number by -2. That is it.
First, plug in the variables
(2*4*9)
Now simplify
(2*4*9)= (8*9)= 72
Your answer would be:
(-x)^2 = 4(-x)+32
or
(-x)^2 = -4x+32
