i = 3c

i = c + 14

set both equations equal to each-other, we can

solve for c, we must.

3c = c + 14

subtract c from both sides, we must.

2c = 14

divide both sides by 2, we must.

c = 7

7 years old, Christopher is.

Answer: Christopher is 7 years old.


Step-by-step explanation: If I were Ishaan's age and C were Christopher's age, if Ishaan is 3 times the age of Chris we can do

I=3c

We also know that Ishaan is 14 years older than Chris. So we can set the equation as:

I=14+c

If we insert I=3c into I=14+c, it is

3c=14+c

2c=14

c=7

Therefore, chris is 7 years old.

Zack wants a new skateboard that costs $98. He has a coupon for 20% off the original price. The sales tax is 6%, what is the fin
svet-max [94.6K]

The final cost of skateboard will be $83.10

Step-by-step explanation:

Given,

Cost of skateboard = $98

Coupon = 20% off

Amount of discount = 20% of cost of skateboard

Amount\ of\ discount=\frac{20}{100}*98\\\\Amount\ of\ discount=\frac{1960}{100}\\\\Amount\ of\ discount=\$19.6

Cost of skateboard after discount = Cost of skateboard - Amount of discount

Cost of skateboard after discount = 98 - 19.6 = $78.4

Sales tax = 6%

Sales tax amount = 6% of discounted price

Sales\ tax\ amount=\frac{6}{100}*78.4\\\\Sales\ tax\ amount=\frac{470.4}{100}\\\\Sales\ tax\ amount=\$4.70

Final cost of skateboard = Discounted price + Sales tax

Final cost of skateboard = 78.40+4.70 = $83.10

The final cost of skateboard will be $83.10

Wen is factoring the polynomial, which has four terms. 6x3 – 12x2 7x – 14 6x2 (x – 2) 7(x – 2) Which is the completely factored
-Dominant- [34]

The completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)

<h3>What is the factor of polynomial?</h3>

The factor of a polynomial is the terms in linear form, which are when multiplied together, give the original polynomial equation as result.

Wen is factoring the polynomial, which has four terms.

6x^3 - 12x^2+ 7x - 14 '

Take out the greatest common factor from the equation and make separate groups as,

6x^2(x - 2)+ 7(x - 2)\\(x-2)(6x^2+7)

Rearrange the above equation as,

(6x^2+7)(x-2)

Thus, the completely factored form of the Wen's polynomial, which has the four terms initial, is,

(6x^2+7)(x-2)
