Answer:
-6 has no solution due to that it is already done
Answer:
one solution; the answer is -3 = x
Step-by-step explanation:
Using the quadratic formula, the solutions are x1 = 1.3416 and x2 = -1.3416
So, it has 2 real solutions.
The area of any triangle = (1/2) x (length of the base) x (height)
2.5 centimeters = 0.025 meter
The area of the sail is (3.75) = (0.5) x (0.025) x (height)
Multiply each side by 2 : (7.5) = (0.025) x (height)
Divide each side by 0.025 : (7.5)/(0.025) = height =<em> 300 meters</em>
The situation is stupid, but the math is bullet-proof.
(x+3)(x+4)
x^2+4x+3x+12
x^2+7x+12
