No because it works for y + x= 9 but not the first one
You can put each into standard form to see whether they have the right value.
5.5·10⁴ = 55,000 ≠ 0.00055
Vertical Angles: Theorem and Proof
Theorem: In a pair of intersecting lines the vertically opposite angles are equal. It can be seen that ray \overline{OA} stands on the line \overleftrightarrow{CD} and according to Linear Pair Axiom, if a ray stands on a line, then the adjacent angles form a linear pair of angles.
Answer:
u = 5
Step-by-step explanation:
9(u+2) = 63
9(5+2) = 63
9(7)=63

Answer:
4xy
Step-by-step explanation:
List the prime factors of each term.
- 4xy = 2·2·x·y
- 8x^2y = 2·2·2·x·x·y
- 24x^4y^5 = 2·2·2·3·x·x·x·x·y·y·y·y·y
Identify a factor that appears in each list. Cross it off of each list and add it to your list of "output" factors. Repeat until you run out of factors that appear in all of the lists.
You should quickly determine that all of the factors of 4xy appear in both other lists. That is the GCF. When you have exhausted the factors of 4xy, there are no more possible common factors.
GCF = 4xy
Then the expression can be factored as ...
= 4xy·(1 +2x -6x^3y^4)
_____
<em>Additional comment</em>
If you use exponents to simplify writing repeated multiplication, you will find that the GCF has the factors with the lowest exponent. Here, the lowest power of 2 is 2^2 in 4xy; the lowest exponents of x and y are 1, also in that term.
