<span>2a(-4b) + 3a(2a+6b)
= -8ab + 6a^2 + 18ab
= 10ab + 6a^2

6(6a - b) + 2a(b-3) / 2
= 36a - 6b + a(b-3)
= 36a - 6b + ab - 3a
= 33a - 6b +ab

-1/3 (12c-9d)
= -4c + 3d </span>

Determine the constant that should be added to the binomial so that it becomes a perfect square trinomial. Then write and factor
Nesterboy [21]

Answer:

$64, \ (x+8)^2$

Step-by-step explanation:

A perfect square trinomial is defined as an expression that is obtained from squaring a binomial equation. The perfect square trinomial is in the form of $ax^2+bx+c$.

The given expression is :

$x^2+16x$

The co-efficient of the x-term in $x^2+16x$ is '16'.

So half of the term 16 ,

$\frac{16}{2} = 8$

and $(8)^2=64$

Now add 64 to the expression:

$x^2+16x+64$

Therefore, the perfect square trinomial is

$(x+8)^2=x^2+16x+64$

To find miles per hour:

3 3/5 miles divided by 4/5 hour

3 3/5 = 5*3 + 3 = 18/5

18/5 divided by 4/5 equals

18/5 times 5/4

The fives cancel out, and we have 18/4 which reduces to 9/2 or 4 1/2 miles per hour :)
