There are 72 green pens.

There is 9 times as many white pens from 2 to 18, so there has to be 9 times as many green pens because of the ratio. 9 times 8 is 72.

Can someone please help me with this problem?
pentagon [3]
The slope would be 0 because if you put in the coordinates with the formula, you would get the slope as 0. This also makes sense because both points have the same y point, so that means that the line wasn’t travelling up or down. And since it was only going through -8 that would be the y-intercept.

(3x + 5)(x2 + 6x +11)<br> multiply
viva [34]

Answer:

3x³ + 23x² + 63x + 55

Step-by-step explanation:

Given

(3x + 5)(x² + 6x + 11)

Each term in the second factor is multiplied by each term in the first factor, that is

3x(x² + 6x + 11) + 5(x² + 6x + 11) ← distribute both parenthesis

= 3x³ + 18x² + 33x + 5x² + 30x + 55 ← collect like terms

= 3x³ + 23x² + 63x + 55

A triangle has sides of 6 m 8 m and 11 m is it a right-angled triangle?​
rewona [7]

Answer:

No

Step-by-step explanation:

If we use the Pythagorean theorem, we can find if it is a right triangle. To do that, set up an equation.

6^{2}+8^{2}=c^2

If the triangle is a right triangle, c would equal 11

Solve.

36+64=100

Then find the square root of 100.

The square root of 100 is 10, not 11.

So this is not a right triangle.

I hope this helps!

Question:

Solution:

Let the function

y=f(x)\text{ = }\sqrt[]{x}-9

Now remember the following rule:

To graph y = f(cx)

if 0 < c < 1 , stretch the graph of y = f(x) horizontally by a factor of 1/c.

Thus, applying this to the given function, with c = 3, we can conclude that the correct answer is:

y=f(x)\text{ = }\sqrt[]{\frac{1}{3}x}-9
