The solid figure is a rectangular prism.
Step-by-step explanation:
- A rectangular prism is a solid figure that has 12 faces. Each face is in the shape of a rectangle. It is also called a cuboid.
- Along a length of a side, it has the same cross-section. This is what makes it a prism.
- All its edges also meet at right angles or 90°.
- Volume of a rectangular prism = length × width × height
Take 1/2 of 1 and square it and add to both sides
1/2 squared=1/4, add to both sides
x^2+x+1/4=19/4+1/4
factor perfect square
(x+1/2)^2=20/4
(x+1/2)^2=5
square root both sides
x+1/2=+/-√5
minus 1/2 both sides
x=-1/2+/-√5
x=-1/2+√5 or
x=-1/2-√5
B is answer
The answer is 0.01 seconds it would take for five seconds
