Answer:

-5x^4 +6x^3 -x +3

Step-by-step explanation:

First, eliminate parentheses.

(-4x^3+5x^2-x+3)-5(x^4-2x^3+x^2)

= -4x^3 +5x^2 -x +3 -5x^4 +10x^3 -5x^2

Then collect terms.

= -5x^4 +(-4+10)x^3 +(5 -5)x^2 -x +3

= -5x^4 +6x^3 -x +3

A cube has 6 congruent square faces

The area of 1 face = $\frac{2}{3}$ × $\frac{2}{3}$ = $\frac{4}{9}$

Multiply by 6 to obtain surface area of cube

surface area = 6 × $\frac{4}{9}$ = $\frac{24}{9}$ = $\frac{8}{3}$ units²

Ashley has $9.05 in dimes and nickels. If she has a total of 108 coins, how many of each type does she have?

klemol [59]

Answer:

$73\:\mathrm{dimes},\\35\:\mathrm{nickels}$

Step-by-step explanation:

We can write the following system of equations:

$\begin{cases}10d+5n=905,\\d+n=108,\\\end{cases}$ , where $d$ is the number of dimes she has and $n$ is the number of nickels she has.

Multiply the second equation by $-5$ and add both equations to solve for $d$ :

$\begin{cases}10d+5n=905,\\-5d-5n=-540,\\\end{cases}\\5d=365,\\d=\fbox{$73$}$ .

Plug $d=73$ into any equation to solve for $n$ :

$73+n=108, \\n=\fbox{$35$}$
