Answer:

Hey there!

a)

10x-1=4x+2

6x-1=2

6x=3

x=1/2 cm.

10x-1=4 cm.

So the width of the rectangle is 10/4, or 2.5 cm.

b)

l=3w

2l+2w=24

2(3w)+2w=24

6w+2w=24

8w=24

w=3

l=9

The are is 27 units squared.

Let me know if this helps :)

A body is moving along a straight line with a velocity which varies according to the equation v = 9 t2 + 2t, where v is in feet
kaheart [24]
V(t) = 9t² + 2t
To find a function for distance as a function of time:

Using Calculus:
Take the integral of V(t)
This means find the anti-derivative (if v(t) is the derivative of d(t), what must d(t) be?)
d (t) = (1/3)*9* t ²⁺¹ + (1/2) * 2 * t¹⁺¹ 
d(t) = 3t³ + t² + C

Answer is B) 3t³ + t² + C.

Why did we add C at the end? The velocity function doesn't tell us anything about our initial distance, so we add C to account for wherever we started at t=0. This is also known as our Constant of Integration

constant coefficient is that which have no variable but in the opinion of the student the coefficient is 3 which have a variable x.
