Answer:
x=4
Step-by-step explanation:
to get rid of the square root on the right you square both sides so
2x+8=x^2
Then bring
2x+8
to the left so you have 0=(x^2)−2x+8
Now you can do the quadratic formula to find the zeroes
Answer:
<em>The probability that it would contain at least 6 letters is: </em><u><em>5/8</em></u>
<u><em></em></u>
Step-by-step explanation:
From the question given above,
We know that there are 8 planet that was given.
Mercury 7 letters
Venus 5 letters
Earth 5 letters
Mars 4 letters
Jupiter 7 letters
Saturn 6 letters
Uranus 6 letters
Neptune. 7 letters
Therefore,
P(at least 6 letters) + P( Less than 6 letters) = 1
P (at least 6 letters) + P (3 planet) = 1
P (at least 6 letters) + ( 3/8) = 1
P(at least 6 letters) = 1 - (3/8)
= 5/8

Cos 12 = sin (90 - 12) = sin 78
-7/-9 is equivalent to -14/-18. Multiply the denominator and numerator by the same number(I used 2)
