Factor the following: 7k^2+3k-10

Answers

Step-by-step explanation:

7k² + 3k - 10

= 7k² + ( 10 - 7 ) k - 10

= 7k² + 10k - 7k - 10

= k( 7k + 10 ) - 1( 7k + 10)

= ( 7k + 10) ( k - 1)

Hope it will help :)

Answer:

Step-by-step explanation:

Use the Pythagorean Theorem to determine the roots

k = 1,-10/7

7k^2+3k-10 = 7(k-1)(k+10/7) = (k-1)(7k+10)

A chemical compound requires 8 ounces of chemical A and 12 ounces of chemical B. A mixture contains 24 ounces of chemical A and 30 ounces of chemical B. How can you fix the mixture to make the chemical compound?

Answers

Add 6oz of chemical B and remove 1/3 of the total mixture.
I might always be wrong.
Explanation:
Since 8x3=24 and since 12x3=36 you need to add 6oz of chemical B to have 24oz of chemical A and 36oz of chemical B.
Take 1/3 of the total mixture to have 8oz of chemical A and 12oz of chemical B.

cars the students wash. Write an inequality that represents the situation.

Answers

Answer:

14c + 61 is greater than or equal to (put the greater than symbol with the line underneath there) 600

The inequality for raising the money will be written as 14c + 61 > 600.

What is inequality?

When two expressions are connected by a sign like "not equal to," "greater than," or "less than," it is said to be inequitable. The inequality shows the greater than and less than the relation between variables and the numbers.
