Answer:
x = 2
Step-by-step explanation:
3x + 4 - x = 8
Combine like terms
2x + 4 = 8
-4 from both sides
2x = 4
Divide by 2
x = 2
For question 11, you essentially need to find when h(t) = 0, since that is when the height of the ball reaches 0 (ie touches the ground).
For question 12, it is asking for a maximum height, so you need to find when dh/dt = 0 and taking the second derivative to prove that there is maximum at t. That will find you the time at which the ball will hit a maximum height.
Rinse and repeat question 12 for question 13
The other part of your ratio is missing
A parallelogram is a quadrilateral with two opposite sides equal in lengths while a rhombus is a parallelogram with the two sets of opposite sides equal to each other. A rhombus forms perpendicular bisectors when <span>diagonals are intersected with each other. Answer then is A</span>
