Answer:
C
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
A hexagon has 6 sides, so n = 6
sum = 180° × (6 - 2) = 180° × 4 = 720° → C
Answer:
-4x3y2
-2x3y2
x3y2
6x3y2
Step-by-step explanation:
Like terms are the parts of an equation which have the same variables and exponents.
The term 4x3y2 has x and y specifically x3 and y2. Only terms with this same base and exponent values are like terms.
x2y3
----> NO
4x3y3
----> NO
-4x3y2 -----> x3y2
-2x3y2
-----> x3y2
-4x2y2
----> NO
x3y2
-----> x3y2
6x3y2-----> x3y2
You can do part a using The Pythagoras theorem:-
30^2 = x^2 + 24^2
x^2 = 30^2 - 14^2 = (30+24)(30-24) = 324
x = 18
Answer:
firt thing i would do is take out things that are alike but if these are the options then i would a) multiply the first equation by -1
Our answer is
Our greatest common factor, or GCF, is
, so when we factor is out, our divide each term by
, we get our answer. To check this, we can multiply the
back across the parenthesis and see if we get the same result as our initial question.
Hope this helped! :))
