Answer 1

Answer:

C

Step-by-step explanation:

(x+7)(x+1)(x+4)=

x^3+12x^2+39x+28 or C

Answer 2

Answer:

C

Step-by-step explanation:

Given

(x + 7)(x + 1)(x + 4) ← expand the second/ third factors using FOIL

= (x + 7)(x² + 5x + 4)

= x(x² + 5x + 4) + 7(x² + 5x + 4) ← distribute both parenthesis

= x³ + 5x² + 4x + 7x² + 35x + 28 ← collect like terms

= x³ + 12x² + 39x + 28 → C

PEMDAS (parenthesis, exponents, multiplication, division, addition, subraction)

Answer:

x = 7

Step-by-step explanation:

So first, multiply everything inside the (   ) by 2

So then, the equation will look like this: 3x + 8 + 12x = 113

Then, combine like terms, which leave the equation to look like this:

15x + 8 = 113

Then subtract 8 from both sides, leaving the equation like this : 15x = 105

Last step, divide both sides by 15, which leave you with x = 7

Answers

Answer:

Total cost= $12,300

Giving the following information:

Fixed cost= $1,500

Monthly cost= $450

To calculate the total cost, we need to use the following formula:

Total cost= fixed cost + unitary variable cost*x

x= number of units

For 2 years:

Total cost= 1,500 + 450*24

Your restaurant bill is $42.16. You want to leave a 20% tip. What is your best
estimate of a 20% tip?
Your answer

Answers

Answer:

$8.40

Step-by-step explanation:

Since this is an estimate, you need to do it in your head. The way I did it was I divided 40 by 5 since 20% is one fifth of 100%, then I divided 2 by 5 and added them together which equaled 8.40.

Answer:

About $8

Step-by-step explanation:

Move decimal point one place to the left (making $4.20), then double that answer (making $8.40). You said estimate so I rounded down to $8 but a more precise answer would be $8.40.
