A) Perimeter of Trapezium = 8+5+6+15.5
= 34.5in
Area= 1/2*(a+b)*h
=1/2*(8+15.5)*4
=47in^2
B)Perimeter= 12+6+8.5
=26.5mm
Area=1/2*b*h
=1/2*12*4
=24mm^2
The other leg must be > 0.
Also the third side must be less than the sum of the 2 equal sides.
So the range for the third side x is 0 < x < 30
Unless you meant that sum of the 2 equal sides is 15 in which case the answer is
0 < x < 15.
Answer:x^2+10x+24
Step-by-step explanation:
Area of rectangle=length x width
Area of rectangle=(x+4)(x+6)
Area of rectangle=x^2+6x+4x+24
Area of rectangle=x^2+10x+24
Answer: a. 888 tickets b. 2339 tickets
Step-by-step explanation:
From the question, raffle tickets were sold for a school fundraiser to teachers and students. A total of 1451 tickets were sold to the students and 563 less tickets were sold to teachers than to Students.

a. Tickets sold to teachers = 1451 - 563 = 888
888 ticket were sold to the teachers.
b. Total tickets sold = Tickets sold to students + Tickets sold to teachers
= 1451 + 888
= 2339
