Answer:
The answer is C
Step-by-step explanation:
Answer:
3(3x^2 + 5)
Step-by-step explanation:
step 1: find out the greatest common factor (GCF) of the number 9 and 15
ex: 9x^2 + 15x (3 * 3x^2 + 3 * 5)
step 2: factor out the common term 3
ex: 3 * 3x^2 + 3 * 5 (3 * 3x^2 + 5)
step 3: simplify the equation
3 * 3x^2 + 5 [3(3x^2 + 5)]
X is an odd number
x+2 is also odd (consider the example x = 3 so x+2 = 3+2 = 5). Adding 2 to any odd number is always odd
Similarly, so is x+6 (since we have x+2+2+2).
And so is x+10 (x+2+2+2+2+2).
So every value in this list is an odd number. The middle most values are x+2 and x+6 which are both odd.
Adding any two odd numbers together yields an even number. For example 3+5 = 8. Divide this even number in half and we may or may not get an odd number (eg: 8/2 = 4 and 6/2 = 3)
So this statement is sometimes true
All of these angles can be compared to each other.
There are:
- Alternate interior angles
-- Angles that share one line and two parallel lines and are less than 90 degrees (angles 10, 12). These angles are equal to each other.
- Alternate exterior angles
-- Angles that share one line and two parallel lines and are more than 90 degrees (angles 1,5) These angles are equal to each other.
- Vertical Angle
-- Angles that share a point and are opposite of that point (angles 2,3) These angles are equal to each other.
-Supplementary angles
-- Angles that are on the same side of one line and share the side of another (angles 9,10). These angles are always equal to 180 degrees.
Using this we know:
a. m of angle 5 = to the m of angle 3 = 102
m of angle 5 = 102 degrees
