Answer: 3x² - 2x - 5
Step-by-step explanation:
The area of a rectangle is simply length * width. Thus, simply multiply them, and FOIL.
(3x - 5) (x + 1)
3x ^2 + 3x - 5x - 5
Combine like terms
3x² - 2x - 5
Hope it helps :) and let me know if you want me to elaborate.
[67.9 %, 82.1 %] is the answer when it has 95% confidence interval for the proportion of test-takers who answered the question correctly. So the 95% confidence interval for the proportion of test takers is [67.9 %, 82.1 %] who answered the question correctly, In order to random sample of 144 test-takers and 75% answered question correctly. So the answer in this question is [67.9 %, 82.1 %].

Answer:
x = 4
Step-by-step explanation:
The sum of two interior angles in a triangle is equal to an exterior angle that is supplementary to the third interior angles
46 + (-1 + 8x) = 18x + 5
46 - 1 + 8x = 18x + 5
45 + 8x = 18x + 5 export like terms to the same side
45 - 5 = 18x - 8x
40 = 10x divide both sides by 10
x = 4
