Answer:
21 k^9
Step-by-step explanation:
(3k^4) (7k^5)
Multiply the coefficients

Answer:
a) The area of the triangle AQB is 43 square centimeters.
b) The length of the line segment AQ is approximately 14.866 centimeters.
Step-by-step explanation:
a) The procedure consist in subtracting the areas of triangles APQ, ASB and BRQ of the area the rectangle, that is to say:
The area of the triangle AQB is 43 square centimeters.
b) The length of the line segment AQ is determined by Pythagorean Theorem:
(1)
The length of the line segment AQ is approximately 14.866 centimeters.
