(5x + 3y)(x - 5y)
5x*x = 5x2
5x*-5y = -25xy
3y*x = 3xy
3y*-5y = -15y2
= 5x2 - 22xy - 15y2
Answer: 55 inches
Step-by-step explanation:
Area of a trapezium is calculated by a + b/2 h
Where a is the base 1 given as 6inches
B is also a base 2 given as 14 inches
h is the height given as 5.5inches
Slot the values into the formula:
Area = (6 + 14/2) × 5.5
A= 20/2 × 5.5
A= 10 × 5.5
Area = 55inches
Answer:
The ratio of the first sequence is 2.5 so the recursive formula is going to be an= 2.5(an-1)
