What is 5 times the sum of 7 and 23 in numerical expression
vitfil [10]
5(7 + 23) because you are multiplying 7 + 23 by 5. This is a numerical expression because it has numbers and opperations. This is not an algebraic expression because there are NO variables. Hope this helps :)

What is the completely factored form of f(x)=x3+5x2+4x−6?
Gre4nikov [31]
f(x)=x^3+5x^2+4x-6
f(-3)=(-3)^3+5(-3)^2+4(-3)-6=0\implies x+3\text{ is a factor of }f(x)

Synthetic division yields

-3  |  1   5   4   -6
.    |      -3  -6    6
- - - - - - - - - - - - -
.    |  1   2  -2    0

which translates to

\dfrac{x^3+5x^2+4x-6}{x+3}=x^2+2x-2

with remainder 0. Now by the quadratic formula,

x^2+2x-2=0\implies x=\dfrac{-2\pm\sqrt{2^2-4(1)(-2)}}2=-1\pm\sqrt3

and so

f(x)=x^3+5x^2+4x-6=(x+3)(x-(-1+\sqrt3))(x-(-1-\sqrt3))

The annual tuition at a public two year college last year was $3200. for the new school year, elizabeth first year in college th
Andrej [43]

The <em><u>correct answer</u></em> is:

$280 per month.

Explanation:

Increasing the tuition by 5% means taking 100% of the original number plus an additional 5%; 100+5 = 105% of the original amount.

105% = 105/100 = 1.05; to find 105% of 3200 we multiply it by 1.05:

3200(1.05) = 3360

Since she saved the same amount monthly, we divide the expected total by 12 to find this amount:

3360/12 = 280
