You are given similarity. At this stage the diagram will tell you which sides correspond to which sides.

AC / DF = BC / EF
3 / 5 = 8 / 2x Cross multiply
3 * 2x = 5 * 8 Multiply
6x = 40 Divide by 6
x = 40 / 6
x = 6 4/6
x = 6 2/3
6 2/3 answer <<<<<<<

Determine the quotient, q(x), and remainder, r(x) when

Vinvika [58]

ANSWER

Quotient:

$q(x) = 4 {x}^{2} + 3x + 2$

Remainder:

$r(x) = 3x + 1$

EXPLANATION

The given functions are

$f(x) = 12 {x}^{4} + 21 {x}^{3} + 31 {x}^{2} + 21x + 9$

and

$g(x) = 3 {x}^{2} + 3x + 4$

We want to find the remainder and quotient when f(x) is divided by g(x).

We perform the long division as shown in the attachment.

The quotient is

$q(x) = 4 {x}^{2} + 3x + 2$

The remainder is

$r(x) = 3x + 1$

Which of the following triangles are impossible to draw? Choose all that apply.

ioda

I would say a triangle with two right angles because a triangle's angles add to 180 degrees. If a triangle has two right angles, it means that two angles will be 90 degrees, which add to 180 degrees. A triangle must have three angles and sides, and it is not possible for the last angle to be 0 degrees.

Hope this helps

I need help with please

Tcecarenko [31]

Answer:

x - 2

Step-by-step explanation:

2x - 1 + 4x - 11

First, you want to combine like terms.

We can see that the one and eleven can go together, so add them together.

2x + 4x - 12

The reason that we made one, and eleven, negative twelve, is because they are both being subtracted from the numbers before that.

6x - 12

We added the 2x, and the 4x together to make 6x.

Another way to write this would be x - 2, because you can simplify it by dividing it by 6.

For the function f(x)=5x2−5x, evaluate and simplify.

Marianna [84]

Answer:

10x -5 +5h

Step-by-step explanation:

Use the function definition with the given arguments.

$\dfrac{f(x+h)-f(x)}{h}=\dfrac{(5(x+h)^2-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{(5(x^2+2hx+h^2)-5(x+h))-(5x^2-5x)}{h}\\\\=\dfrac{5x^2+10hx+5h^2-5x-5h-5x^2+5x}{h}=\dfrac{10hx-5h+5h^2}{h}\\\\=\boxed{10x-5+5h}$
