27. (-2 + √-8) + (5 - √-50) standard form ?​

Mathematics
1 answer:
marin [14]3 years ago
3 0

We can break this down by removing the parenthesis first:

-2 + \sqrt{-8} + 5 - \sqrt{-50}

In order to continue, you have to simplify the square roots by factoring it and taking out i:

-2 + 2i\sqrt{2} + 5 - 5i\sqrt{2}

Combine like terms:

-3 - 3i\sqrt{2} <-- that's the answer

Hope I helped :)

Zoe has 5 pounds of potatos she has multiple recipes that require 3/4 pound of potatoes how many recipes will she be able to mak
Natali [406]
Amount of potatoes that Zoe has = 5 pounds
Quantity of potatoes that Zoe need for each recipe = 5/(3/4) 
                                                                                 = 5 * (4/3) 
                                                                                 = 20/3 
                                                                                 = 6 2/3 
From the above deduction, we can conclude that only 6 recipes can be made. The remaining amount of 2/3 will remain unused. I hope the procedure is clear enough for you to understand.

If ab= 7x-6 and bc= 12-2x. Then what does ac equal?
ra1l [238]
Ab = (7x-6) →   b = (7x-6)/a   (1)

bc = (12-2x) → b = (12-2x)/c   (2)

Since (1) = (2) → (7x-6)/a = (12-2x)/c OR  a/c = (7x-6)/(12-2x)  (3)

Multiply  both numerators of (3) by the SQUARE of their  respective denominators;

(a*c²)/c = (7x-6)(12-2x)²/(12-2x)
Now simplify:

ac = (7x-6)(12x-2x)  or ac = -14x² + 96x - 72

What is m&lt;4? I tryed to do the work but I just can't get it can someone help me plz
Mars2501 [29]
M<6 is 60
Since AC and BD are parallel, <6 and <4 are supplementary.
supplementary means = 180 degrees
Since m<6 is 60 degrees, subtract 60 from 180 to get <4
180 - 60 = 120

M<4 is 120

hope this helps
