<h3>What is a equation?</h3>
An equation is a mathematical statement showing the equivalence of two mathematical expressions. Example -
3x + 5 = 8
Given is -
3x² - 7 = 31
2x² + 18 = 0
4x² - 26 = - 50
2x² + 36 = x²
We have -
3x² - 7 = 31
3x² = 38
x² = 38/3
x² = 12.67
x = ±3.56
2x² + 18 = 0
2x² = - 18
x² = -9
x = ±3i
4x² - 26 = - 50
4x² = - 24
x² = -6
x = ±√6i
2x² + 36 = x²
x² = - 36
x = ±√6 i
Therefore, the quadratic equations are solved above.

Answer:
Circle = 7
Pentagon = 8
Square = 12
Square + Square + Square = 36
Step-by-step explanation:
Since you know the circle is 7, the square plus the pentagon must be 20. That means the pentagon in the third equation is 8. This means the square is 12.
So, 12 + 12 + 12 = 36.
Answer:
2 and 11/45
Step-by-step explanation:
If the fraction is improper you have to turn it into a mixed number. You can simplify the mixed number so the answer is 2 and 11/45.
