2x²-5x-3 = 0
(2x+1) (x-3) = 0
2x+1 = 0
2x = -1
x = -½
x-3 = 0
x = 3
then x = -½ , x= 3
Answer:
157.08m²
Step-by-step explanation:
Since the area of a circle is A=πr²
The radius is 10, so
A=π10²
A=314.16 (rounded to nearest hundredth)
Half of that is 157.08.
The answer is E=mc², Einstein's revolutionary formula.
4x+16=-2
Subtract 16 from both sides
4x=-18
Divide both sides by 4
x=-18/4
x= -9/2
Final answer: x=-9/2
