Ax^2 + bx + c
a = 1
b = -4
c = -5
x^2 -4x-5
-5x1 = -5
-5+1 = -4
(factors of c that also add up to b)
ANSWER: (x-5) (x+1)
Answer:
7.0 mi
Step-by-step explanation:
see the attached figure to better understand the problem
step 1
Find the measure of angle C
Remember that the sum of the interior angles in any triangle must be equal to 180 degrees
so
substitute the given values
step 2
Find the measure of a
Applying the law of sines
substitute the given values
solve for a
Answer:
A. (8/30)(22/29)(21/28)
Step-by-step explanation:
The key is in reading the question really thoroughly, like, way more than you would expect. The <em>first</em> person is from the group of 8, thus (8/30), but the other <em>two</em> <u>cannot</u> be from the group of 8. 30(students total) minus 8 (the 8 people from science class)=22 (remaining in math). You choose one person who is <em>not</em> from the group of 8, and you are left with 21 other people. The number of students available to be in a group goes down each time: 30 down to 29 down to 28 (the denominators). Kaboom, A. (8/30)(22/29)(21/28).
