Answer:yeeting is the way to do it
Step-by-step explanation:
If
has to be a solution of the equation, just plug it in:
![(\pm 15i)^2 + [1] = 0 \iff -225 + [1] = 0 \iff [1] = 225](https://tex.z-dn.net/?f=%20%28%5Cpm%2015i%29%5E2%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20-225%20%2B%20%5B1%5D%20%3D%200%20%5Ciff%20%5B1%5D%20%3D%20225%20)
So, the solutions of
are
If the lowest temp. is 60 degrees the highest temp i would think would be i don't know maybe 80 or 70 degrees i don't know though might be wrong sorry if you get it wrong
Answer:
x = 5
Step-by-step explanation:
11. <C=46 degrees
<D = - 1+8x
<B = 180 - (18x+5)
<C + <D + <B = 180 degrees
46 - 1 + 8x + 180 - 18x - 5 = 180
-8x = 180 - 180 -46 +1 +5
-8x = -40
x = -49/-8
x = 5
