Answer:

4x² - 21x - 18

Step-by-step explanation:

Use FOIL.

(x-6)(4x+3)\\\\x*4x = 4x^2\\\\x * 3 = 3x\\\\-6 * 4x= -24x\\\\-6 * 3 = -18\\\\\\4x^2+3x-24x-18\\\\\boxed{4x^2-21x-18}

Hope this helps.

Answer:

4x² - 21x - 18

Step-by-step explanation:

This is a quadratic expression

SOLVING:

(x - 6)(4x + 3)

x(4x + 3) -6(4x + 3)

4x² + 3x - 24x - 18

collecting like terms

<u>4x² - 21x - 1</u><u>8</u>

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute. What percent of the company’s total employ
frosja888 [35]

Answer:

30%  of the company’s total employees telecommute

Step-by-step explanation:

Masco Industries has 285,000 total employees. Of those employees, 85,500 telecommute.

To find the percentage of company’s total employees telecommute

We divide the number of employees telecommute by total employees

Then we multiply by 100 to get percentage

Percentage = \frac{number \ of  \ telecommute \ employess}{total \ employees} * 100

Percentage = \frac{85500}{285000} * 100

Percentage = 0.3 * 100 = 30%

Consider an angle with a measure of θ=225∘.
wel

Answer:

cos 225° = -\frac{\sqrt{2} }{2}

sin 225° = -\frac{\sqrt{2} }{2}

tan 225° = 1

Step-by-step explanation:

I cannot sketch a diagram, but a 225° angle is a 3rd quadrant angle and the reference angle is 45°   (225 - 180 = 45)

cos and sin are negative in the 3rd quadrant and the tan is positive

cos 225° = - cos 45° = -\frac{\sqrt{2} }{2}

sin 225° = -sin 45° = -\frac{\sqrt{2} }{2}

tan 225° = tan 45° = 1

lara [203]
Discount, as you are lowering the item price from 100%  (Default ) to 75% 


Discount = 100% - 75% = 25%

If it was required to find the discount.

discount = 0.25 x Price.

newPrice = 0.75 x Price

Original price = Discount + new Price.
