Check my answer!Factor completely: 6x2 – 12x – 18.

A. 3(2x + 3)(x – 1)
B. (3x + 3)(3x – 3)
C. 6(x + 1)(x – 3)
D. 6(x – 1)(x – 3)

The answer would have to be C. or D.

Answers

Factor out a 6

6 / 6x^2 = x^2
6 / -12x = -2x
6 / -18 = -3

6(x^2 - 2x - 3)

Multiply the first term to the last
1 x -3 = -3

(a x b) = -3
(a + b) = -2 (middle term)

(1 x -3) = -3
(1 + -3) = -2

Plug them in by replacing -2x and simplify

6(x^2 - 1x - 3x - 3)
6((x^2 - 1x) - (3x - 3))
6(x(x - 1) - 3(x - 1))
6(x - 3)(x - 1)

Or in this case, 6(x - 1)(x - 3)

An airplane flies a distance of 650km at an average speed of 300 km/h. How much time did the flight take?

Answers

To solve this, you can set up a proportion and cross multiply.

$(650)/(x)= (300)/(1) \n \n 650*1=300*x \n \n 650=300x \n \n 2.17=x$

2.17 hours

Distance x speed = time
300 x 650
=195000
Checking
Distance divide time = speed
195000 divide 600
=300

You deposit $200 in a savings account. The account earns 6% simple interest per year. A. What is the interest earned after 2 years.
B. What is the balance after 2 years.

Answers

200 x 1.06^2
=224.72

Answer:

A. $24

B. $224

Step-by-step explanation:

For simple interest, the formula is I = PRT where I = interest earned, P = principal amount borrowed/deposited, R = rate as a decimal, and T = time in years.

I = (200)(0.06)(2)

I = 24

Then add that to the amount deposited ($200) and you're done.

200 + 24 = $224

Use the substitution method to solve the system of equation.choose the correct ordered pair. 2x+3y=29
x=4

Answers

I’m not sure if the 2 is counted in the equation or not

Since x=4, substitute it for x in the other equation

4+3y=29
3y=25
Y=8.333333333

2(4)+3y=29
8+3y=29
3y=37
y=12.33333333
