Answer:
Step-by-step explanation:
The time in seconds, required for an object accelerating at a constant rate of a meters/second to travel a distance of d meters is given by this equation.
t = va
We need to find the expression for d in terms of t and a.
As velocity = distance/time
So, the distance d is 
.
<h2>9x^4 - 6x^2 - 3x - 6</h2><h2 />
(9x^4-13x^3-x-7)+(7x^3-2x+1)
Sort the terms by their powers, as x's with the same powers can be added together:
9x^4
-13x^3 + 7x^3 = -6x^3
-x - 2x = -3x
-7 +1 = -6
<h2>9x^4 - 6x^2 - 3x - 6</h2>
Answer: 6m, 10m, and 21m
Step-by-step explanation:
The two smaller sides have to add to be greater than the third side. 6+10 is 16 which is smaller than 21.
