Answer:
x = 80°
Step-by-step explanation:
Angle on a straight line = 180°
(x + 40)° + (x - 20)° = 180°
x + 40° + x - 20° = 180°
2x + 20° = 180°
2x = 180° - 20°
2x = 160°
x = 160°/2
x = 80°
Check:
(x + 40)° + (x - 20)° = 180°
(80° + 40°) + (80° - 20°) = 180°
120° + 60° = 180°
180° = 180°
What are you trying to find?
- Simplify :- 1 + - w² + 9w.
Quadratic polynomial can be factored using the transformation 
, where 
are the solutions of the quadratic equation 
.
All equations of the form 
can be solved using the quadratic formula: 
. The quadratic formula gives two solutions, one when ± is addition and one when it is subtraction.
Square 9.
Multiply -4 times -1.
Add 81 to 4.
Multiply 2 times -1.
Now solve the equation 
when ± is plus. Add -9 to 
.
Divide -9+ by -2.
Now solve the equation when ± is minus. Subtract from -9.
Divide 
by -2.
Factor the original expression using 
. Substitute 
for 
and 
for 
.
<h3>NOTE :-</h3>
Well, in the picture you inserted it says that it's 8th grade mathematics. So, I'm not sure if you have learned simplification with the help of biquadratic formula. So, if you want the answer simplified only according to like terms then your answer will be ⇨
This cannot be further simplified as there are no more like terms (you can use the biquadratic formula if you've learned it.)
Answer:
1
Step-by-step explanation:
We will first find the prime factorization of 32 and 39. After we will calculate the factors of 32 and 39 and find the biggest common factor number .
32=2^5
39=3^1*13^1
-
List of positive integer factors of 32 that divides 32 without a remainder.
1,2,4,8,16
List of positive integer factors of 39 that divides 32 without a remainder.
1,3,13
We found the factors and prime factorization of 32 and 39. The biggest common factor number is the GCF number.
So the greatest common factor 32 and 39 is 1.
