Hey there!!
Okay so here are the steps....
(5 + 2i) + (8 - 3i) <---- when we have exponents we should worry about the "i" because it is equal to √-1 but here it isn't the case.
<u>
(13 - i)</u><u /> <----- This is the answer!
<u />I hope this helps! ^__^
Answer: -8+10s-24t+4u
Steps: Multiply the parantheses by -2
-2×4-2×(-5s)-2×12t-2×(-2u)
Multiply the numbers and calculate the product.
-8+10s-2×12t-2×(-2u) → -8+10s-24t-2×(-2u) → -8+10s-24t+2×2u
And you get -8+10s-24t+4u
Hope this helps ʕ•ᴥ•ʔ
The 3 numbers could be 0.5, 1.1 and 4.4.
In the list above, there is only 1 number less than 1. It is 0.5.
The other 2 numbers are larger than 1.
If you add up the 3 numbers you will have exactly 6.
0.5 + 1.1 + 4.4 = 6
the length of a side of a square is the square root of the area
side length = sqrt(164)
side length = 12.8062
Round the answer as needed
since it asks for approximate, it is probably going to be 13 inches
