Answer:
Diameter = 53.41 m
Step-by-step explanation:
2517/15 = 167.8 (circumference)
D=(C/pi)
C/pi = 53.41
D= 53.41
(2x-5y) + (x+y)
= (2x+x) + (-5y+y)
= 3x + (-4y)
= 3x-4y
So option A is the correct one.
5a – 7b + b2 <span>for a = –1 and b = 5.
5(-1) - 7(5) +5^2
= -5 - 35 + 25
= -40 + 25
= -15</span>
Answer:
bottom: 12 x 12 = 144
1st triangle: (12 x 8)/2 = 48
2nd triangle: 48
3rd triangle: 48
4th triangle: 48
144 + 48 + 48 + 48 + 48 = <u>336 cm squared</u>
