Answer:
14 + 25l + 6l^2
Step-by-step explanation:
(7 + 2i) (2 + 3i)
=> 14 + 4l + 21l + 6l^2
=> 14 + 25l + 6l^2
This is the correct answer
Zero.
None of the 14 cm cubes will fit within the 8 cm height.
Answer:
6 dresses
Step-by-step explanation:
Given: sales price is $d
Regular price is 3 times of sales price
Janine has money to buy 2 dresses at regular price.
Now, finding the number of dresses Janine can buy at the sales price, if sale price is d
Regular price= ![3\times d= 3d](https://tex.z-dn.net/?f=3%5Ctimes%20d%3D%203d)
Janine has total money=
(∵ regular price is 3d)
∴ Number of dresses bought by Janine= ![\frac{Total\ money}{sale\ price\ of\ one\ dress}](https://tex.z-dn.net/?f=%5Cfrac%7BTotal%5C%20money%7D%7Bsale%5C%20price%5C%20of%5C%20one%5C%20dress%7D)
⇒ Number of dresses bought by Janine= ![\frac{6d}{d} = 6\ dresses](https://tex.z-dn.net/?f=%5Cfrac%7B6d%7D%7Bd%7D%20%3D%206%5C%20dresses)
∴ Number of dresses bought by Janine is 6.
Since the exponent of the scientific notation is negative −3-3, move the decimal point 33 places to the left.

Hope this Helps.
here,
Q is the midpoint of PR.
O is the midpoint of PN.
So, the line joining the midpoints of two sides is half and parallel to the third side.
So, QO is parallel to NR.
Now,
in triangles OPQ and NPR,
i) angle OPQ = angle NPR (common angle)
ii) angle POQ = angle PNR (corresponding angles)
iii) angle OQP = angle NRP (corresponding angles)
so,
triangle OPQ is similar to triangle NPR.
(by AAA similarity)
