Illusion [34]

A posted speed limit of 55 mph means that: You may drive 55 mph only under favorable conditions.

<h3>What is the speed limit?</h3>

Speed limits on road traffic, as used basically to set the legal maximum speed at which vehicles are permitted to utilize on a given stretch of road.

Now generally, speed limits are normally indicated on traffic signs reflecting the maximum allowable speed in kilometers per hour (km/h) or eevn miles per hour (mph). They are primarily set by the legislative bodies of national or provincial governments and then enforced by law enforcement agencies. This suggests that speed limits varies from road to road and is even absent in some certain areas.

Complete the square to make a perfect square trinomial. Then, write the result as a binomial squared. y^2+10y
VashaNatasha [74]

Answer:

(y+5)²

Step-by-step explanation:

Every perfect square trinomial, completes the rule:

(a+b)²=(a²+2ab+b²)

Let's complete the PST:

(a) would be the square root of y², which is y.

(b) would be a number that multiplied by 2y gives us 10y, which is 5.

Our perfect square trinomial is y²+10y+25

Finally, using the mentioned rule, the binomial square for that equation is (y+5)²
