Answer:

\large\boxed{3\sqrt{16}+\sqrt{-9}=12+3i}

Step-by-step explanation:

3\sqrt{16}+\sqrt{-9}\\\\\sqrt{16}=4\ \text{because}\ 4^2=16\\\\\sqrt{-9}=\sqrt{(9)(-1)}\qquad\text{use}\ \sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\\=\sqrt9\cdot\sqrt{-1}=(**)\\\sqrt9=3\ \text{because}\ 3^2=9\\\sqrt{-1}=i\\(**)=3i\\\\3\sqrt{16}+\sqrt{-9}=(3)(4)+3i=12+3i

Can someone please help me with question 9

There are 24 oranges and 36 apples.

Each basket has to have the same number of fruit

So lets say that each basket will have exactly one orange and apple.

To get the maximum number of baskets, we have to use either all of the apples or all of the oranges.

You can't have 36 baskets, because you only have 24 oranges, even though there are enough apples.

But you can 24 baskets, because there are enough apples and oranges.

So you can use all of the oranges to make 24 baskets  (and you'll be left with 12 apples)

Answer: F. 24.

There is a line that includes the point (5, 6) and has a slope of 0. What is its equation in
Solnce55 [7]

Answer:

y = 0x +6 or y = 6 if simplified

Step-by-step explanation:

y=mx+b is slope intercept formula

m is the slope which we know ( 0 ) and we know the line passes through (5,6) so all we need to figure out is b

so plug it in and solve:

6 = 0(5) +b

6 = b

so 6 is b and now we know the equation

y = 0x +6 or y = 6 if simplified

PLEASE HELP HURRY WITH THE QUESTIONS BELOW!!!!!
AnnZ [28]

From left to right, the answers are:  152, D(line e), C(obtuse), 44 degrees.

Now I feel guilty and sleezy.  Giving answers alone without explanations
is something I almost never do, because it doesn't help anybody do
anything but cheat.  But it's all I have time for right now.  If a mod comes
along and decides to delete this because of no explanations, then let him
delete it.  It'll serve us right, you and me both.
