Hello from MrBillDoesMath!

Answer: 3

Discussion:

The perimeter of a polygon is the sum of the side lengths.

Perimeter of top polygon is (x+2) + 2x + (x + 2) + (4x + 1) = 8x + 5

Perimeter of bottom triangle is 4x + 2x + (3x+2 ) = 9x + 2

The perimeters are the same when

8x + 5 = 9x + 2

Subtract 8x from both sides:

5 = (9x - 8x) + 2 or

5 = x + 2

Subtract 2 from each side to get x = 3:

5 -2 = 3 = x

The perimeter of either figure is 29

Suppose the position of an object moving in a straight line is given by s left parenthesis t right parenthesis equals 5 t square

Tpy6a [65]

Answer:

v(6) = 62

At any given time: v(t) = 10t + 2

Step-by-step explanation:

The equation that describes the position of the object is:

$s(t) =5t^2+2t+2$

The instantaneous velocity at any given time, v(t), is the derivate of the position expression:

$\frac{ds(t)}{dt}=v(t) =10t+2$

For t = 6, the instantaneous velocity is:

$v(6) =10*6+2\\v(6) = 62$

The instantaneous velocity when t=6 is v(6) = 62 units of distance/units of time.
