Answer: 14x - 11

Step-by-step explanation:

Add 10x and 4x.

14x −15 + 4

Add −15 and 4.

14 x −11

OR.

Apply the distributive property. 5 ( 2 x ) + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply 2 by 5 . 10 x + 5 ⋅ − 3 + 4 ( x + 1 )

Multiply 5 by − 3 . 10 x − 15 + 4 ( x + 1 )

Apply the distributive property. 10 x − 15 + 4 x + 4 ⋅ 1

Multiply 4 by 1 . 10 x − 15 + 4 x + 4

hoped this helped lmk if it did

A person invests $4000 at 2% interest compounded annually for 4 years and then invests the balance (the $4000 plus the interest

faltersainse [42]

$\bf \qquad \textit{Compound Interest Earned Amount}

A=P\left(1+\frac{r}{n}\right)^{nt}
\quad 
\begin{cases}
A=\textit{accumulated amount}\\
P=\textit{original amount deposited}\to &\$4000\\
r=rate\to 2\%\to \frac{2}{100}\to &0.02\\

\textit{times it compounds per year}\\
\textit{annually, thus once}
\end{array}\to &1\\
t=years\to &4
\end{cases}
\\\\\\
A=4000\left(1+\frac{0.02}{1}\right)^{1\cdot 4}\implies A=4000(1.02)^4\implies A\approx 4329.73$

then she turns around and grabs those 4329.73 and put them in an account getting 8% APR I assume, so is annual compounding, for 7 years.

add both amounts, and that's her investment for the 11 years.

Paulo's economics course requires two papers ? ?one long and one short ? ?throughout the semester. The number of pages, l l, in

mixer [17]

Answer:

27 pages.

Step-by-step explanation:

Let l be the number of pages in the long paper and s be the number of pages in the short paper.

We have been given that the total number of pages for both papers is 40. We can represent this information in an equation as:

$l+s=40...(1)$

We are also told that the number of pages in the long paper is one more than two times the number of pages in the short paper. We can represent this information in an equation as:

$l=2s+1...(2)$

We will use substitution method to solve system of linear equations.

From equation (1) we will get,

$s=40-l$

Upon substituting this value in equation (2) we will get,

$l=2(40-l)+1$

$l=80-2l+1$

Upon adding 2l to both sides of our equation we will get,

$l+2l=80-2l+2l+1$

$l+2l=80+1$

$3l=81$

Let us divide both sides of our equation by 3 we will get,

$\frac{3l}{3}=\frac{81}{3}$

$l=27$

Therefore, there must be 27 pages in the long paper.

What is x squared minus 4x minus 45

Mazyrski [523]

That's a second-degree expression in 'x'. It represents a number,
but the number it represents completely depends on the value of 'x'.
And if the value of 'x' ever changes, then the value of the whole
expression instantly changes.

The expression is also the product of (x + 5) and (x - 9) .
