when running a line, in a right-triangle, from the 90° angle perpendicular to its opposite side, we will end up with three similar triangles, one Small, one Medium and a containing Large one, from where we can use proportions to get their sides, so Check the picture below.

Can someone help me with factoring? 4x^3 + 43x^2 + 30x

Sergio039 [100]

$4x^{3}+43x^2+30x$
First in factoring, you must find out what is common in the whole equation
$x(4x^2+43x+30)$
Now, make 2 sets of parentheses and "split up" the rest of the equation
Try to experiment which numbers work out
We are not subtracting anything so both parentheses are positive
$x(4x+3)(x+10)$
Therefore, the factored version of $4x^3+43^2+30x$ is
$x(4x+3)(x+10)$

you are making curtains by alternating strips of solid colored fabric and patterned fabric. the solid colored fabric costs 99¢ p

weeeeeb [17]

Hello,

to find the total cost (c) of the colored strips we have to multiply the number of strips (n) by the cost of each color strip (99¢), that as an algebraic function is:

$\boxed{c= n*99}$ [¢]

Now, if we use 3 solid color strips, that means that we use 4 patterned strips, so:

$Cost=3*0.99+4*1.25 \\ \boxed{Cost= 7.97}$

Answer: c=n*99 and Cost per curtain= $7.97

Andre bought a new bag of cat food. The next day, he opened it to his cat. The graph shows how many ounces was left in the bag o

Viktor [21]

Answer:

There were 16 ounces of Cat Food after 24 days.

Step-by-step explanation:

From the graph attached,

For an ordered pair (x, y) lying on the graph,

x-coordinate represents the number of days since bag was bought and y- coordinate represents the ounces of cat food required.

Now the value x = 24 on x-axis shows the number of days since the bag was bought.

For x = 24, ounces of cat food in the bag ( y ) = 16 ounce
