Answer:
38.4 minutes
Step-by-step explanation:
Assuming the error was 20% less
↝ Form into 
where a > 0 (Optional)
↝ Multiply -1 for both sides.
↝ Then proceed with the Quadratic Formula.
x = [-b ± (√b²-4ac)]/2a ↝ Quadratic Formula
↝ As you can see that inside the square root, the numbers cannot be negative. Therefore, the solutions are imaginary.
↝ Solution with Real Numbers System ↝ There are no real solutions.
↝ Solution with Complex Number System ↝
Therefore, the answer for Complex Number System is (5±√7i)/2
Answer:
Step-by-step explanation:
<u>First, the side lengths should be greater than zero:</u>
Second, The triangles have a common side and the given sides are opposite of 27° and 37° angles.
<u>This tells us the side opposite of greater angle is greater:</u>
<u>Simplify each inequality:</u>
- 3x - 5 > 0 ⇒ 3x > 5 ⇒ x > 5/3
- 2x + 3 > 0 ⇒ 2x > - 3 ⇒ x > - 3/2
- 2x + 3 > 3x - 5 ⇒ 3x - 2x < 3 + 5 ⇒ x < 8
<u>Common solution is:</u>

Answer:
125 and 185
Step-by-step explanation:
first u have to use the table values and put them in the linear equation.
so you have in first: w= 7, so: h= 20.7-15-->h=125
and in the last: w=10, so h=20.10-15-->h=185
