Answer:

<u>Rectangle area is the product of its two adjacent sides:</u>

  • A = xy = 14

<u>Find each missing length</u>

  • xy = 14
  • y = 14 / x

1. x = 2 1/3 = 7/3

  • y = 14 ÷ 7/3 = 6

2. x = 4 1/5 = 9/5

  • y = 14 ÷ 9/5 = 70/9 = 7 7/9

3. x = 6/7

  • y = 14 ÷ 6/7 = 49/3 = 16 1/3

What are the roots of the polynomial equation x3-7x=6x-12?
Ilia_Sergeevich [38]
This is not a polynomial equation unless one of those is squared.  As it stands x=-.833.  If you can tell me which is squared I can help solve the polynomial.

Ok, that is usually notated as x^3 to be clear.   I'll solve it now.

x^3-13x-12=0

Then use factor theorum to solve x^3-13x-12/x+1 =0
So you get one solution of x+1=0
x=-1

Then you have x^2-x-12 now you complete the square.

Take half of the x-term coefficient and square it. Add this value to both sides. In this example we have:

The x-term coefficient = −1

The half of the x-term coefficient = −1/2

After squaring we have (−1/2)2=1/4

When we add 1/4 to both sides we have:

x2−x+1/4=12+1/4

STEP 3: Simplify right side

x2−x+1/4=49/4

STEP 4: Write the perfect square on the left.

<span>(x−1/2)2=<span>49/4
</span></span>

STEP 5: Take the square root of both sides.

x−1/2=±√49/4

STEP 6: Solve for x.

<span>x=1/2±</span>√49/4

that is,

<span>x1=−3</span>

<span>x2=4</span>

<span>and the one from before </span>

<span>x=-1</span>

Finley and Cooper are wanting to go to SkyZone. Finley pays $53.75 for 5 hours. How much will Cooper pay for 3 hours?
IrinaK [193]

Answer:

<em>10.75 x 3 = $32.25</em>

Step-by-step explanation:

first, we need to figure out how much the cost is for one hour:

53.75/5 = 10.75

therefore, the cost at skyzone for 1 hour is $10.75 , BUT, we still need to figure out the time for 3 hours.

so, 10.75 x 3 = $32.25
