Answer:
Day 24.
Step-by-step explanation:
Where 3 and 8 have a common multiple will be the day they meet. The multiples of 3 are 1, 3, 6, 9, 12, 15, 18, 21, 24, 27. The multiples of 8 are 1, 8, 16, 24, 32. 24 is a multiple of both. Rami will have both on day 24.
2(4+2x) is equal to 5x+5 because x=3 and if you plug it in, you get 20 for both sides.
I would first add 5 and 2 together, then multiply that by 3. Finally you would subtract the 1. After solving for what is inside the parentheses you would multiply it by 2 for your final answer.
2•(3(5+2)-1)
2•(3(7)-1)
2•(21-1)
2•(20)
40
Answer:
813.75
Step-by-step explanation:
area of a regular polygon = side length × # of sides × apothem × 1/2
here side length = 15 , # of sides = 7 ( a heptagon has 7 sides ) and apothem = 15.5
so area = 15 × 7 × 15.5 × 1/2
==> multiply 15 by 7 by 15.5
area = 1627.5 × 1/2
==> divide 1627.5 by 2
area = 813.75
