Answer:
A
Step-by-step explanation:
40/10 will give you your answer
40/10=4m/s
You can use the quadratic formula with it which will be easier
or simple factoring
it will be (5x-11)(7x+4)
Use the distance formula:

(6, -2), (-2, -12)

⇒


⇒


= 12.8
The distance between points T and U is
12.8 units.
There are 6, you'd think there would be 8 but the answer is actually 6. A diagonal is a line segment that connects to vertices, the two vertices chosen do not count when forming the triangle, two vertices that are adjacent to that chosen vertex are NOT included when forming the diagonal. It's confusing, but I hope this helps. If you have any follow up questions I'd love to answer them.
Step-by-step explanation:
Sum of angles in a triangle = 180°.
Question 3:
We have 90° + 61° + (14x + 1)° = 180°.
=> 14x° + 152° = 180°
=> 14x° = 28°
=> x = 2.
Question 4:
We have 70° + 55° + (4x + 3)° = 180°.
=> 4x° + 128° = 180°
=> 4x° = 52°
=> x = 13.
