Answer:
2a + 30
Step-by-step explanation:
break it down so it is 4(a+5)
then work out -2(a-5)
so 4 x a then 4 x 5 which gives 4a + 20
then -2 x a then -2 x -5 which gives -2a + 10
then when you have 4a + 20 -2a + 10
do 4a - 2a which is 2a
do 20 + 10 which is 30
so the answer comes to 2a + 30
if anything doesnt seem right just comment and i will correct
hope this helps :)
Answer:
Part A: [0,2], Part B: [2, 4], Part C: [8,10], Part D: 0 ft
Step-by-step explanation:
Part A: The time between 0 seconds to 2 seconds is the time when it's increasing. There is no other time like that.
Part B: The graph shows a straight line so therefore it is staying the same.
Part C: The graph shows a sharp decline.
Part D: Starting from the 10th second, the balloon already hit to ground so it would only make sense for it to stay there...
You have to simplify and then get x
The answer would be C.(-2,-3); Minimum.
You can tell be cause the points are going down<span />
Answer:
x = 5
Step-by-step explanation:
6/18 = x/(20-x)
1/3 = x/(20-x) Multiply both sides by 20-x
(20-x)/3 = x Multiply both sides by 3
20-x = 3x Add x in both sides
20 = 4x Divide both sides by 4
5 = x
