7x^2 - 16x - 8 = 0
using the quadratic formula x = [ -(-16)+/- sqrt((-16^2 - 4*7-8] / 2*7
= (16 +/1 sqrt 480) / 14
= 2.71, -0.42 to nearest hundredth
Answer:
241,920 different ways
Step-by-step explanation:
We have 6 vowels, but A repeats twice and I repeats three times, so the number of ways in which each can either start or end the word:
³P₂ = 3! / (3 - 2)! = 6 / 1 = 6 ways
You can start words with A, E or I, or end the words with A, E, or I.
the remaining 8 consonants can be arranged in 8! ways = 40,320 ways
total number of ways that the letters can be arranged = 6 x 40,320 = 241,920 different ways

Step-by-step explanation:
i dont see any thing
11a^3 + 6 - (-7a^3 + 7)....distribute the - through the parenthesis
