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:

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.

Given
The length of a rectangle ABCD =
= 
The width of a rectangle =
= 
so the expression of the area of rectangle ABCD as simplified polynomial will be:

![A=\left[\left(x+5\right)\:+\:\left(3x\right)\:+\:\left(4x-9\right)\right]\:\times \left[2x\right]](https://tex.z-dn.net/?f=A%3D%5Cleft%5B%5Cleft%28x%2B5%5Cright%29%5C%3A%2B%5C%3A%5Cleft%283x%5Cright%29%5C%3A%2B%5C%3A%5Cleft%284x-9%5Cright%29%5Cright%5D%5C%3A%5Ctimes%20%5Cleft%5B2x%5Cright%5D)




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

Hence, the 2nd option is correct.
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
