Answer:
Area of a triangle = A =
Step-by-step explanation:
Given Data:
height of a triangle = h = 15 in
base of a triangle = b = 2 feet = 2*12 =24 in
To Find Out:
Area of a triangle = A = ?
Formula:
Area of a triangle = A = 
Solution:
Area of a triangle = A = 
Area of a triangle = A = 
Area of a triangle = A = 
Area of a triangle = A =
Answer:
Ill do this quick...
Its B.
Step-by-step explanation:
A square root can’t be a negative value, so the root would be greater than or equal to zero.
Range:
Y>=O
[O, infinity)
To find the value of r
We will follow the steps below
Usinf the equation of a slope:
slope(m) =

from the question given;
m= -3/4
x₁ = 3
y₁=4
x₂=-1
y₂=r
substituting the values into the slope formula

we can now simplify and then solve for r

cross-multiply
-3 x -4 = 4(r-4)
12 = 4(r-4)
Divide both-side of the equation by 4

3 = r - 4
add 4 to both-side of the equation
3+4 = r-4+4
7 = r
r=7
Therefore the value of r is 7
