Answer:

a. (x+2)(x+3)

b. x = -2

x = -3

Step-by-step explanation:

split 5x into 2x + 3x

then, you get

x² + 2x + 3x + 6

Split into (x² + 2x) + (3x + 6)

factorize individual groups

x (x + 2) + 3 (x + 2)

combine x + 3

your final answer is

(x + 2) (x + 3)

if (x + 2) (x + 3) = 0

then (x+2) = 0 and (x+3) = 0

x + 2 = 0

x = -2

x + 3 = 0

x = -3

Viktor [21]

a. The salary of the department head is $105,000.

b. The salary of president is $420,000.

Step-by-step explanation:

Let,

x be the salary of president.

y be the salary of head of department.

According to given statement;

x=4y

a) What is the salary of the department head?

Salaries of two heads of department = $210000

$2y=210000$

Dividing both sides by 2;

$\frac{2y}{2}=\frac{210000}{2}\\y=105000$

The salary of the department head is $105,000.

b) What is the salary of the president of the university?

x=4y

$x=4(105000)\\x=420000$

The salary of president is $420,000.

9 pt = How much fl oz

____ [38]

Answer:

9 pints would equal 144 ounces

Step-by-step explanation:

Pints

The US liquid pint is a unit of fluid volume equal to one-eighth of a gallon, one-half of a quart, or two cups. The liquid pint should not be confused with the dry pint (US) or the imperial pint, which are different units.

The pint is a US customary unit of volume. Pints can be abbreviated as pt; for example, 1 pint can be written as 1 pt.

Fluid Ounces

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as an "ounce" but should not be confused with the unit of mass. One fluid ounce is equal to just under 29.6 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[1]

The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as fl. oz. or oz. fl.. For example, 1 fluid ounce can be written as 1 fl oz, 1 fl. oz., or 1 oz. fl..

FrozenT [24]

Answer:

7480 hours

Step-by-step explanation:

440 - 100 = 340

LCM of 440 and 340

440 = 2 × 2 × 2 × 5 × 11

340 = 2 × 2 × 5 × 17

LCM = 2 × 2 × 2 × 5 × 11 × 17

LCM = 7480
