Answer:

$6(x-10)(x+9)$

Step-by-step explanation:

First, make A equal one by factoring out the greatest common factor, 6. This makes the new expression $6(x^{2} +x-90)$ . Then, factor the remaining polynomial by finding two numbers that multiply to -90 and add to 1. These two numbers are -10 and 9. So, add each term to x and then multiply to get the final answer, $6(x-10)(x+9)$ .

Carpet costs $12 per square yard. How much will it cost to carpet a room that is 180 square feet?

Evgen [1.6K]

Converting units from feet to yards is easy. However, it becomes tricky when converting square yard to square feet but it is easy if you get the gist of it. Simply square both sides of the conversion:

Since 3 feet = 1 yard
(3 feet)^2 = (1 yard)^2
9 feet^2 = 1 yard^2

In the same way, if you want to convert from cubic feet to cubic yard, simply cube (raise to the power of 3) both sides. :)

While traveling in a car, the centrifugal force a passenger experiences as the car drives in a circle varies jointly as the mass

rjkz [21]

Answer:

A- 129.6 N

Step-by-step explanation:

Since the centrifugal force on the passenger, F varies jointly as the mass of the passenger, m and the square of the speed of the car,v. In mathematical notation, F ∝ mv² ⇒ F = kmv².

If F₁ = 226.8 Newtons, m₁ = 70 kilograms and speed v₁ = 60 kilometers per hour. From F= kmv², k = F/mv² the proportionality constant. If F₂ is the force on the passenger of mass m₂ = 90 kilograms and speed of car ,v₂ = 40 kilometers per hour. Then,

$k = \frac{F_{1} }{m_{1}v_{1} ^{2} } = \frac{F_{2} }{m_{2}v_{2} ^{2} }\\ F_{2} = F_{1} \frac{m_{2} }{m_{1} }(\frac{v_{2} }{v_{1} }) ^{2} \\F_{2} = 226.8\frac{90 }{70 }(\frac{40 }{60 }) ^{2}\\F_{2} = 129.6 newtons$
