Answer:
(12 × 4) = 24 square feet
Step-by-step explanation:
The shaded triangle's area is found using the formula for the area of any triangle, A = 1/2 b*h. The base of the triangle is the longest side 12 ft. The height is 4 ft.
A = 1/2 *12*4 = 6*4 = 24 square feet
This is the solution though the expression is missing the 1/2.
(12 × 4) = 24 square feet
Answer:
Perimeter = 25
Step-by-step explanation:
J(-2, 5)
K(1, 1)
L(1, -1)
M(-5, -4)
N(-5, 1)
Formula for distance between 2 coordinates is;
d = √((x_2 - x_1)² + (y_2 - y_1)²)
Thus;
JK = √((1 - (-2))² + (1 - 5)²)
JK = √25
JK = 5
KL = √((1 - 1)² + (-4 - 1)²)
KL = √25
KL = 5
LM = √((-5 - (-1))² + (-4 - (-1))²)
LM = 5
MN = √((-5 - (-5))² + (1 - (-4))²)
MN = 5
JN = √((-5 - (-2))² + (1 - 5))²)
JN = 5
Thus;
Perimeter = 5 + 5 + 5 + 5 + 5
Perimeter = 25
C
The construction described creates the incenter of the circle and this point is equidistant from all vertices of a triangle.
u( t - 2s)
double s is expressed as 2s
subtract this result from t gives t - 2s
multiply this result by u gives u × (t - 2s) = u( t - 2s)
