Answer: A trapezoid is always a parallelogram.
Step-by-step explanation:
I set Jon an equation and solved for number of hours
Consecutive integers are 1 apart
they are
x,x+1,x+2
so it would be
x+x+1+x+2=45
B is answer
Answer:
Solution given:
b=9 base side of isosceles triangle
a=
1+3+5+7+...+999 =
= 1+2+3+4+...+500
+1+2+3+...+499
= 2·(1+2+3+...+499) + 500
= 2·(499·500)/2 + 500
= 499·500 + 500
= 500·(499 + 1)
= 500·500
= 250.000
