2. 2n-5=7
+5+5 no makes it 2n=12 do 12/2 and you get 6 and thats your answer hope i helped
The angles in a triangle add up to 180, so its
5x+2+6x-10+4x+8=100, then you combine it, so its
15x=180, then divide 180 by 15, and you get 12.
Then insert that into each equation.
4(12)+8= 56
5(12)+2= 62
6(12)-10= 62
They all add up to 180 and two of the angles have the same measure, which makes it an isosceles triangle.
Answer:
Over 5 days, the pool loses 11
inches of water.
Step-by-step explanation:
Since the leaky pool is losing water at a rate of 2 inches of water each day, than we can find the amount of water the pool has lost over 5 days, by either adding 2 five times, or just multiplying 2 by 5:
2 x 
So, the total amount of water lost over 5 days is 11 inches.
Answer:
(328i + 82) / 17
Step-by-step explanation:
`(2i(4+5i)(4-5i))/(4+i)
= (2i(16 - 25i^2)) / (4 + i)
= (2i( 16 + 25) )) / (4 + 1) [Note:- i^2 = -1]
= 82i / (4 + i)
= 82i(4 - i) / (4 + i)(4 - 1)
= 328i + 82 / (16 - i^2)
= (328i + 82) / 17
