Answer:
x = -5 ±4sqrt(3)
Step-by-step explanation:
(x + 5)^2 = 48
Take the square root of each side
sqrt((x + 5)^2) = ±sqrt(48)
x+5 = ±sqrt(16*3)
x+5 = ±4sqrt(3)
Subtract 5 from each side
x = -5 ±4sqrt(3)
Answer:
34/55
Step-by-step explanation:
Find the probability of the opposite; not a single vowel chosen.
So, the consonants are 7, so 7/11 times 6/10, which is 21/55.
Then, just 1 - 21/55 to get 34/55
Subtract 7 from both sides
4x = -9 - 7
Simplify -9 - 7 to -16
4x = -16
Divide both sides by 4
x = -16/4
Simplify 16/4 to 4
<u>x = -4</u>
