Answer:
120°.
Step-by-step explanation:
The sum of all interior angles in a polygon with 
sides (
, 
) is equal to 
. (Credit: Mathsisfun.)
The polygon here has 6 sides. 
. Its interior angles shall add up to 
.
Consider the properties of a regular polygon. (Credit: Mathsisfun.)
- All sides in a regular polygon are equal in length.
- All angles in a regular polygon are also equal.
There are six interior angles in a polygon with 6 sides. All six of them are equal. Thus, each of the six interior angle will be
.
Answer:
The answer is D. -3, 6, 11
Step-by-step explanation:
A coefficient is a number used to multiply a variable.
Example: 6z means 6 times z, and "z" is a variable, so 6 is a coefficient. Variables with no number have a coefficient of 1.
Example: x is really 1x.
4x+5 = 8x - 11
4x - 8x = -11 - 5
-4x = -16
x = 4
4x+5 = 4(4) +5 = 21
8x - 11 = 8(4) - 11 = 21
<RST = 21 + 21 = 42
answer
<RST = 42 degrees
Answer:
D) 12x² - 20x + 7
Step-by-step explanation:
Use FOIL when multiplying 2 binomials...
FOIL is Firsts, Outsides, Insides, Lasts. It's the order in which you multiply the numbers in the binomials...
(2x - 1)(6x - 7)
Firsts: (2x)(6x) = 12x²
Outsides: (2x)(-7) = -14x
Insides: (-1)(6x) = -6x
Lasts: (-1)(-7) = 7
Now add them up...
12x² - 14x - 6x + 7
12x² - 20x + 7
