Answer:
x = 14
Step-by-step explanation:
1.1 Pull out like factors :
2x - 20 = 2 • (x - 10)
Equation at the end of step 1 :
Step 2 :
Equations which are never true :
2.1 Solve : 2 = 0
This equation has no solution.
A a non-zero constant never equals zero.
Solving a Single Variable Equation :
2.2 Solve : x-10 = 0
Add 10 to both sides of the equation :
x = 10
One solution was found :
x = 10
Answer:
49×66+49×34 = 49× (66+34)
Let's solve this problem step-by-step.
STEP-BY-STEP SOLUTION:
We will be using simultaneous equations to solve this problem.
First we will establish the equations which we will be using as displayed below:
Equation No. 1 -
A + B = 90°
Equation No. 1 -
A = 2B + 12
To begin with, let's make ( A ) the subject in the first equation as displayed below:
Equation No. 1 -
A + B = 90
A = 90 - B
Next we will substitute the value of ( A ) from the first equation into the second equation and solve for ( B ) as displayed below:
Equation No. 2 -
A = 2B + 12
( 90 - B ) = 2B + 12
- B - 2B = 12 - 90
- 3B = - 78
B = - 78 / - 3
B = 26°
Then we will substitute the value of ( B ) from the second equation into the first equation to solve for ( A ) as displayed below:
A = 90 - B
A = 90 - ( 26 )
A = 64°
ANSWER:
Therefore, the answer is:
A = 64°
B = 26°

Answer:
12 units
Step-by-step explanation:
Allow me to revise your question for a better understanding and I hope it will fit the original one.
The parallelogram shown below has an area of 72 units squared. The base is 6 and the other side is 13 Find the missing height.
Here is my answer:
Given:
The area: 72 units squared.
The base: 6 units
As we know that the area of the parallelogram is represented by below formula:
A = b*h where h is the height and b is the base
In this situation, we know:
72 = 6*h
<=> h = 12
So the missing height is 12 units
Step-by-step explanation:
The value of n=12
The question might be wrong but according to your question this is the right answer
