Explanation

•  45 should be added to 631 to make it a perfect square number.
• ***

Step-by-step explanation:

if we can add 45 then it becomes

631+45=676

√676=26 that's why

answer is

45

Explanation

Solution for 4x+5 -17=0 equation

4x + 5 = 17

4x = 17 - 5

4x  = 12 (divide both sides by 4 to get x)

4x/4 = 12/4

x = 3

Explanation

14 ---- 400 x ----- 600 ___________ Using BCM

we have, 14*600 = 400*x

Solving the equation, we have 8400/400 = x

So, 21 = x,

Or, x = 21

Step 1: Find the speed of the train

Distance = 60 km
Time = 1.5 hours

Speed of train=601.5/​=40 km/h

Step 2: Find the speed of the plane

The plane travels twice the speed of the train:

$$\text{Speed of plane}=2\times 40=80\text{ km/h}$$

Step 3: Convert 20 minutes into hours

20 min=20​.60=1/3​ hour

Step 4: Calculate the distance travelled by the plane

$$\text{Distance}=\text{Speed}\times \text{Time}$$=80×1/3= 80/3​≈26.67 km
