Answer:
linear equation has two variables doesn't involve any power
quadratic equation involves one of the variables raised to the second power.
Step-by-step explanation:
A <u>linear equation</u> in two variables doesn't involve any power higher than one for either variable. It has the general form Ax + By + C = 0, where A, B and C are constants. ... A <u>quadratic equation</u>, on the other hand, involves one of the variables raised to the second power.
4x² - (2x + 3)²
4x² - (2x + 3)(2x + 3)
4x² - (2x(2x + 3) + 3(2x + 3))
4x² - (2x(2x) + 2x(3) + 3(2x) + 3(3))
4x² - (4x² + 6x + 6x + 9)
4x² - (4x² + 12x + 9)
4x² - 4x² - 12x - 9
-12x - 9
-3(4x) - 3(3)
-3(4x + 3)
Answer:
1 - True

3 - False
4 - True
Step-by-step explanation:
N/A
395 *25% could also be interpreted as 395/4
395 = 98.75
4
4% of $8000 is $320 x 9 = $2880
The answer is $2880
