Subst. the given x and y values: 6(-1)^4 * (3)^3
6 * 27 = 162

Note that you MUST do the exponentiation first.

Also note that your post would be much clearer if you'd please use " ^ " to denote exponentiation: 6x^4 * y^3

Please complete the following problem

Easy, just use the good ol' formula A = L x W x H

3 x 6 x 4 = 72

You can cramp 72 cubic feet of dirt in that hole.

I'm not sure why you want to put hole in a dirt. did you kill somebody? think about it

Biff is 25 years older than Hannah today. Four years from now,Biff will be 6 times as old as Hannah will be. How old is Hannah t

gavmur [86]

Hannah is 1 year old today.

Step-by-step explanation:

Let,

Hannah = x

Biff = y

According to given statement;

y = x+25 Eqn 1

In four years;

y+4 = 6(x+4) Eqn 2

Putting value of y from Eqn 1 in Eqn 2;

$(x+25)+4=6x+24\\x+25+4=6x+24\\x+29=6x+24\\29-24=6x-x\\5=5x\\5x=5$

Dividing both sides by 5

$\frac{5x}{5}=\frac{5}{5}\\x=1$

As x is age of Hannah, therefore,

Hannah is 1 year old today.
