Area is length times width. In this case, if we use all 3300 feet of fence, the width (distance from the river to the fence opposite can be x, and the fence opposite the river will be 3300-2x (the total amount of fence, less the amount on the other two sides) so the area as a function of x to meet the specification of the problem will be:<span>
A(x)=x(3300−2x)=(43560)20</span><span>
It looks to me that you could turn it into a quadratic equation (ax^2+bx+c=0) and solve it....

I hope my answer has come to your help. Thank you for posting your question here in Brainly. We hope to answer more of your questions and inquiries soon. Have a nice day ahead!

One number is 1/4 of another number. The sum of the two numbers is 5. Find the two numbers. Use a comma to separate your answer
masha68 [24]

Answer: 1, 4

Step-by-step explanation:

  • Number #1 = x
  • Number #2 = \frac{1}{4} x

\frac{1}{4} x+x=5\\\\\frac{1}{4} x+\frac{4}{4} x=5\\\\\frac{5}{4} x=5\\\\5x=4*5\\5x=20\\x=4

  • Number #1 = x = 4
  • Number #2 = \frac{1}{4} x = \frac{1}{4} *4=\frac{4}{4} =1

What is the rule to represent the number of tiles in figure x?
dezoksy [38]
Figure 1 has 8 tiles
figure 2 has 14 tiles
figure 3 has 22 tiles

I'm guessing the 2 on the side hints for us to do something+2
the inside parts are
figure 1: 6
figure 2: 12
figure 3: 20

hmm, the width is 1+number figure
height is 2+figure number

so therefor, figure x is (1+x)(2+x)+2

so the rule is figure x has (x+1)(x+2)+2 or x^2+3x+4 tiles



a. the rule is figure x has (x+1)(x+2)+2 or x^2+3x+4 tiles
b. it is quadratic because it has x^2 in it

6. In Diagram 1, NPQRSTUV is a regular octagon. NVW and STW are straight lines.
Sveta_85 [38]

Answer:

  A.  37.5°

Step-by-step explanation:

∠SPT can be considered an inscribed angle in the circumcircle. In that circle, arc ST would have a measure of 360°/8 = 45°. Angle y° is half that measure, so is 22.5°.

The external angles of a regular octagon are 360°/8 = 45°, so that is the measure of angles UTW and UVW. It is also the amount by which reflex angle TUV exceeds 180°.

The sum of the interior angles of quadrilateral TUVW is ...

  45° +225° +45° +3x° = 360°

Then 3x° = 45° and x° = 15°.

Then the sum of interest is ...

  x° + y° = 15° + 22.5° = 37.5°
