Answer:

Step-by-step explanation:

x^2 + x - 12

12 = 4*3,

We have -12 so 4 or 3 should be negative.

+ x , coefficient = +1 , so we have +4 - 3 = +1

(x+4)(x-3)

We can check:

(x+4)(x-3) = x^2 + 4x - 3x -12 = x^2 + x - 12

At total of 2 feet of snow falls over three days on the first day 1/6 of the snow falls on the second day 7/12 of the snow falls

ioda

Answer:

$Day\ 3 = 1\frac{3}{12}$

Step-by-step explanation:

Given

$Total = 2ft$

$Day\ 1 = \frac{1}{6}$

$Day\ 2 = \frac{7}{12}$

Required

Determine the amount of snow on day 3

This can be calculated using:

$Day\ 1 + Day\ 2 + Day\ 3 = Total$

Substitute values for the known parameters

$\frac{1}{6} + \frac{7}{12} + Day\ 3 = 2$

Collect Like Terms

$Day\ 3 = 2 - \frac{1}{6} - \frac{7}{12}$

Take LCM

$Day\ 3 = \frac{24 - 2 - 7}{12}$

$Day\ 3 = \frac{15}{12}$

Express as mixed number

$Day\ 3 = 1\frac{3}{12}$

Imogene invested $8,000 in a bank account that pays 8 percent simple interest at the end of each year. Her friend invested the s

Natali5045456 [20]

The right system of equations to describe the situation would be on the form:

x1 = 8000 + y1*t

and

x2 = 8000 + y2*t

where x1 and x2 represents the total money of Imogene and her friend respectively at the end of t years.

Now for the value of amount earned, y1 and y2:

y1=8000*0.08

y2=2000*√(t-2)

blondinia [14]

Answer:

1,216 cm³

Step-by-step explanation:

Volume (composite space figure) = Volume (pyramid) + volume (prism)

⇒ [16 x 6 x 14 / 3] + [16 x 6 x 8]
⇒ 96 [14/3 + 8]
⇒ 96 [14/3 + 24/3]
⇒ 96 x 38/3
⇒ 32 x 38
⇒ 1,216 cm³
