Triss [41]

Answer:

  1675 cm

Step-by-step explanation:

distance = speed · time

total distance = speed1 · time1 + speed2 · time2

 = (40 cm/s)(25 s) + (15 cm/s)(45 s) = 1000 cm + 675 cm = 1675 cm

Answer:

The expression of the area of rectangle ABCD as simplified polynomial will  be:

A=16x^2-8x

Hence, the 2nd option is correct.

Step-by-step explanation:

As we know that the area of a rectangle can be obtained by multiplying the length by the width.

i.e.

A=l\times w

Given

The length of a rectangle ABCD = l = (x+5) + (3x) + (4x-9)

The width of a rectangle = w = 2x

so the expression of the area of rectangle ABCD as simplified polynomial will  be:

A=l\times w

A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]

   =\left(\left(x+5\right)+\left(3x\right)+\left(4x-9\right)\right)\left(2x\right)

   =\left(x+5+3x+4x-9\right)\times \:2x

   =2x\left(8x-4\right)

    =16x^2-8x

Therefore, the expression of the area of rectangle ABCD as simplified polynomial will  be:

A=16x^2-8x

Hence, the 2nd option is correct.

Find &lt; SPT in degrees
kupik [55]

Answer: 108deg

From picture:

10z=pi and m<SPT =6z So we know 20z=2pi or 360deg

Let’s solve:

20z=2pi

z=pi/10

m<SPT=6z=6pi/10=3pi/5 now lets take the angle from radians to degrees by unit conversion:

3pi/5*(180deg/pi)=108deg
