Step-by-step explanation: ME NEED POINTZ
Answer:
9, 30, 27
Step-by-step explanation:
To find the perimeter, you must add up each side. In this scenario, we know that the perimeter is 66 feet. We also know the sides, which are n, 3n+3 and 4n-9.
So, we must add the sides to get 66 feet.
n+3n+3+4n-9=66
Combine like terms, and solve:
(n+3n+4n)+(3+-9)=66
8n+-6=66
8n-6=66
n=9
So if n=9, we can easily find the value of the other sides.
3(9)+3=30 feet.
4(9)-9=27 feet
So, the sides are 9, 30, and 27 feet (in order).
Answer:
the angles are supplementary. x=20
<span>A store display rotates 40 times every half hour i.e 30 minutes
Thus, by simple calcultion, we say,
Therefore, the store display rotates 80 times in 1 hour i.e. 60 minutes
Now,
Thus, the strore display will rotate 80*4 = 320 times in 4 hours
therefore, the answer is 320 times in 4 hours</span>
