<u>Answer:</u>

3 (2x-5)(x+2)

<u>Step-by-step explanation:</u>

We are given the following quadratic expression:

6x^2-3x-30

and we are to solve this by factorizing.

For that, we will take 3 as a common and factorize the rest of the expression.

6x^2-3x-30

3(2x^2-x-10)

Findinf factors of (2x^2-x-10) such that when multiplied they give a product of -20 and when added they give a result of -1:

3(2x^2+4x-5x-10)\\\\3((2x(x+2)-5(x+2))\\\\3(2x-5)(x+2)

Therefore, the factors of the given expression 6x^2-3x-30 are 3(2x-5)(x+2).

A brand new filled jar of salsa is 11 cm tall and a has a radius of 6 cm. Kelly eats some of the salsa and the salsa in the jar
Sonbull [250]

Before we begin please note that a jar is always cylindrical in shape if not mentioned otherwise. Thus, we will take a cylindrical jar in this case.

Since Kelly eats some of the salsa and the salsa in the jar is now 6 cm high, we know that Kelly ate the amount of Salsa whose volume is missing from the jar.

To find the missing volume on the Salsa jar all that we need to do is to find the height of the missing volume which is given to us as h= 6 cm. We already know that the radius of the jar, r=6 cm. Thus, the amount of Salsa Kelly has eaten is:

V=\pi(6)^2\times 6\approx678.6\approx679 cm^3

Thus, the third option is the correct answer

Please answer this correctly
Ilya [14]

Answer:

The mode would decrease by 3

Step-by-step explanation:

The mode right now is 6, as there are 4 6's. However, closely behind it is 3, with 3 3's. If we replaced a 6 with a 3, we would have 4 3's and 3 6's. Find the difference between 6 and 3 and you answer should be 3.

If I rencently decreased my average number of products sold per week by 15% I now sell an average of 21.25 products per week. Pr
VladimirAG [237]

Alright, lets get started.

Suppose previously I was selling product per week = x

As per question, I have decreased my average number of product by 15 %

Means I have decreased number of product by : x * 15 % = x * 0.15 = 0.15 x

So, the new average product = x - 0.15 x = 0.85 x

As per given question, the new average product = 21.25

0.85 x = 21.25

Dividing by 0.85 in both sides

0.85 x / 0.85 = 21.25 / 0.85

x = 25

Hence it means, 25 products were selling previuosly. : Answer

Hope it will work :)
