Answer:
We have the equation
First, we want the same denominator in both equations, so we can multiply in the left by 5, and in the right bt -ab, and now we have:
Now we have all in the same rational.
The only restriction in this type of equation is that the denominator never can be zero.
so 15*a*b = 0 is a restriction:
This means that a can not be zero, and b can not be zero.
Shaded area = Area of circle - 2(area of one triangle)
The circle has radius 5 cm, so its area is
The triangle has a base of 6 cm. Two of its legs coincide with the radius of the circle, which means the height of the triangle must be 5 - 1 = 4 cm. So one triangle's area would be
.
Shaded area =
.
So the simplest way to think of this is that if 1 mile takes 6.2 minutes, 26.2 miles can be multiplied by 6.2 to find the total time. <span />

W=16
L=18
SA=2(288+1296+1152)
SA=5472 square inches

Answer:
Perimeter of PQR = 37 units (Approx.)
Step-by-step explanation:
Using graph;
Coordinate of P = (-2 , -4)
Coordinate of Q = (16 , -4)
Coordinate of R = (7 , -7)
Find:
Perimeter of PQR
Computation:
Distance between two point = √(x1 - x2)² + (y1 - y2)²
Distance between PQ = √(-2 - 16)² + (-4 - 4)²
Distance between PQ = 18 unit
Distance between QR = √(16 - 7)² + (-4 + 7)²
Distance between QR = √81 + 9
Distance between QR = 9.48 unit (Approx.)
Distance between RP = √(7 + 2)² + (-7 + 4)²
Distance between RP = √81 + 9
Distance between RP = 9.48 unit (Approx.)
Perimeter of PQR = PQ + QR + RP
Perimeter of PQR = 18 + 9.48 + 9.48
Perimeter of PQR = 36.96
Perimeter of PQR = 37 units (Approx.)
