3m² = 3 - 8m
0 = 3m² + 8m - 3
0 = (3m - 1 )(m + 3)
m = -3, 0.33
Answer:
No!
Step-by-step explanation:
This question is essentially asking if =
Well we can easily tell that it doesn't, but if we want to check, we can do cross multiplication.
So we are trying to find out if 5(4) = 3(6).
5(4) = 20 and 3(6) = 18.
so
They are not equal!
Answer:
3x
Step-by-step explanation:
n, n + 2, n + 4, n + 6 - four consecutive odd integers
3 times the largest decreased by 19 is twice the second integer
3(n + 6) - 19 = 2(n + 2) <em>use distributive property</em>
(3)(n) + (3)(6) - 19 = (2)(n) + (2)(2)
3n + 18 - 19 = 2n + 4
3n - 1 = 2n + 4 <em>add 1 to both sides</em>
3n = 2n + 5 <em>subtract 2n from both sides</em>
n = 5
n + 2 = 5 + 2 = 7
n + 4 = 5 + 4 = 9
n + 6 = 5 + 6 = 11
<h3>Answer: 5, 7, 9, 11</h3>
Angle x would be 40 since if you add the 2 known degrees 60 and 80 you would get 140, and since a triangle will always be 180 degrees added together and when you subtract 140 from 180 you will get 40 which will be the last angle
