B. Spend 10 percent on entertainment and 20 percent on clothing

C. Spend 10 percent on rent and 10 percent on food

D. Spend 20 percent on food and 5 percent on gas.

Answer:

Spend 10% on clothing and 10% on entertainment

Step-by-step explanation:

Before answering this question, you need to know 2 types of expenses:

1. Fixed

2. Variable

Fixed expenses is the obligatory expenses which we do not have much control, and usually we have to pay in a certain amount of type. For example rent, student loan, grocery etc. In this case, the only fixed expenses is rent which you have to pay every month.

The other options: entertainment, clothing,food and gas are considered variable as it is not obligatory and you can choose how much you would spend.

Option C is not applicable since rent is a fixed expenses and can't be easily change.

Between A, B and C, A is the less amount of percentage compared the other.

Factor completely, then place the answer in the proper location on the grid. <br> 6х^2 - 3х - 30
Tems11 [23]

Answer:

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

Step-by-step explanation:

Given

6x² - 3x - 30 ← factor out 3 from each term

= 3(2x² - x - 10) ← factor the quadratic

Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term

product = 2 × - 10 = - 20 and sum = - 1

The factors are + 4 and - 5

Use these factors to split the x- term

2x² + 4x - 5x - 10 ( factor the first/second and third/fourth terms )

= 2x(x + 2) - 5(x + 2) ← factor out (x + 2) from each term

= (x + 2)(2x - 5), thus

2x² - x - 10 = (x + 2)(2x - 5) and

6x² - 3x - 30

= 3(x + 2)(2x - 5) ← in factored form
