Answer:
x² = 35
Step-by-step explanation:
This expression as an equation is x² = 35
<em>x</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>power</em><em> </em><em>is</em><em> </em><em>x²</em>
<em>Therefore</em><em> </em><em>x</em><em> </em><em>to</em><em> </em><em>the</em><em> </em><em>second</em><em> </em><em>power</em><em> </em><em>equal</em><em> </em><em>to</em><em> </em><em>35</em><em> </em><em>as</em><em> </em><em>an</em><em> </em><em>equation</em><em> </em><em>is</em><em> </em><em><u>x²</u></em><em><u> </u></em><em><u>=</u></em><em><u> </u></em><em><u>35</u></em>
Answer:
AO and OC
x+8 and 16-x
x+8 = 16-x
x+x= 16-8
2x= 8
x= 8/2
x=4
DO and OB
2y+13 and 5y+4
2y+13 = 5y+4
2y-5y= 4-13
-3y = -9
y= 9/3
y= 3
Step-by-step explanation:
i hope this helps
if this helps let me know
Answer:
it started with ob thats all i know if it did like this answer
Step-by-step explanation:
Using the quadratic formula, we solve for
.

Taking square roots on both sides, we end up with

Compute the square roots of -171 + 140i.


By de Moivre's theorem,

and the other root is its negative, -5 - 14i. We use the fact that (140, 171, 221) is a Pythagorean triple to quickly find

as well as the fact that


(whose signs are positive because of the domain of
).
This leaves us with

Compute the square roots of 5 + 12i.


By de Moivre,

and its negative, -3 - 2i. We use similar reasoning as before:




Lastly, compute the roots of -2i.



as well as -1 + i.
So our simplified solutions to the quartic are

Answer:
6 cartons
Step-by-step explanation:
4 is 40% of 10
so you need to find 40% of 15
15*.4=6
.4 is equal to 40%
