10 tenths are equivalent to 1
Answer:
Hello
Here's the answer:
2x^2 + 5x + 2 = 0\\ 2x^2+4x+x+2=0\\ 2x(x+2)+1(x+2)=0\\ (2x+1)(x+2)=0\\ x=-\frac{1}{2} \vee x=-2
x^2-4x+1=0\\ x^2-4x+4-3=0\\ (x-2)^2=3\\ x-2 =\sqrt3 \vee x-2=-\sqrt3\\ x=2+\sqrt3 \vee x=2-\sqrt3
Step-by-step explanation:
Answer:
45 degrees/360 degrees=1/8
So the area would be 1/8 *100=100/8=25/2
Step-by-step explanation:
The equation is 4x+8=-12 so you subtract 8 from both sides to give you 4x=-20, then you divide by 4 to get x=-5
Volume =πr²h
192π = πr²(12) // Plug the value of the volume and the height in
r² = 192π ÷ 12π // divide by 12π on both sides
r² = 16 // Simplify
r = √16 // square root both sides
r = 4
