Answer:
See below ~
Step-by-step explanation:
<u>Question 1</u>
- (2 + 3i) + (3 - 4i)
- <u>5 - i</u>
<u>Question 2</u>
- (3 – 5i) – (–2 – i)
- 3 - 5i + 2 + i
- <u>5 - 4i</u>
<u>Question 3</u>
- (2 − 4i)(1+ 3i)
- 2 - 4i + 6i - 12i²
- <u>14 + 2i</u>
<u>Question 4</u>
- 2i(-1 + 3i)
- -2i + 6i²
- <u>-6 - 2i</u>
Factor out the trinomial. Find factors of x² and 6 that would, when added, give you 5x
x² = x * x
6 = 3 * 2
(x + 3)(x + 2) are your binomials.
To solve for x, set each parenthesis = 0
x + 3 = 0
x + 3 (-3) = 0 (-3)
x = -3
x + 2 = 0
x + 2 (-2) = 0 (-2)
x = -2
x = -3, -2

Answer: 8:12 and 36:54
Step-by-step explanation:
Answer:
6
Step-by-step explanation:
So to find how much sheep there were on each acre, you divide.
250/40
You do this because you are splitting the 250 sheep into 40 acres.
250/40 = 6.25
There cannot be .25 of a sheep, and since it says on average the answer does not need to be exact. So you would round it off to 6 as your answer.
Since they give you the graph find the highest point in the curved line:
the line touches the number 100
so it's maximum height is 100 feet
now from where it touches 100 look at the time:
it hits 100 feet at 2.5 seconds
