Step-by-step explanation:

I am not critically certain but the ways you have jotted down your enquiry..

<h2>I assume is</h2>

13 × (4×11)

13 × 44

=572 - 44= 528

528+13 =541

541 ×13=7033

sarah spent a total of 10 on oranges and apples at the supet market. if she spent 3 dollars less for oranges than she did on app

beks73 [17]

Let's write 2 equations from the two statements given.

<em>Sarah spent 10 dollars on both oranges and apples</em>

<em />

Let the price of oranges be "x" and price of apples be "y", thus we can write:

$x+y=10$

Oranges cost 3 less than apples, thus we can say:

$y-3=x$

We can substitute this into the first equation and solve for y:

$\begin{gathered} x+y=10 \\ y-3+y=10 \\ 2y=10+3 \\ 2y=13 \\ y=\frac{13}{2} \\ y=6.5 \end{gathered}$

Thus, let's solve for x now,

$\begin{gathered} x=y-3 \\ x=6.5-3 \\ x=3.5 \end{gathered}$

We want the price of oranges (x), thus,

<em>Price of Oranges = $3.50</em>

SOMEONE PLEASE HELP ME I DONT KNOW HOW TO DO THIS AT ALL

Lina20 [59]

Answer:

$y=2cos(4\pi x)\\
$

Step-by-step explanation:

Since the amplitude of the cosine function is 2, I would put the multiply it by 2. There is no phase shift

The period is 1/2, so it would be 4pi

Plug them in into y=Acos(Bx), y=2cos(4pix)

Factor the expression.

g100num [7]

Answer:

(x + 1) (3 x^2 + 1)

Step-by-step explanation:

Factor the following:

3 x^3 + 3 x^2 + x + 1

Factor terms by grouping. 3 x^3 + 3 x^2 + x + 1 = (3 x^3 + 3 x^2) + (x + 1) = 3 x^2 (x + 1) + (x + 1):

3 x^2 (x + 1) + (x + 1)

Factor x + 1 from 3 x^2 (x + 1) + (x + 1):

Answer: (x + 1) (3 x^2 + 1)
