Answer:

6ft by 40ft

Step-by-step explanation:

Perimeter = 2(L+W)

Area = LW

L is the length of the fence

W is the width

Given

P = 68ft

A = 240ft²

Substitute into the formula

68 = 2L+2W ... 1

240 = LW... 2

From 1;

34 = L+W

L = 34-W ... 3

Substitute 3 into 2

From 2;

LW = 240

(34-W)W = 240

34W - W² = 240

- W²+34W = 240

W²-34W - 240 = 0

W²+6W-40W - 240 = 0

W(W+6)-40(W+6) = 0

W-40 = 0

W = 40feet

Since

34 = L+W

34 = L + 34

L = 6ft

Hence the dimension of the fence is 6ft by 40ft

Answer:

its height.=44cm

If you divide any number by 1, the answer will come out the same as the number you are trying to divide.

Answer:

Y=-5.6

x=.9

Step-by-step explanation:

Isolate the x:

6x=11+y

2x=7-3y

multiply top by 3 to get rid of y(3y and -3y cancel each other out)

18x=11

2x=7

put them together:

20x=18

divide by 20

x=0.9

to find y plug in x to the first equation:

y=6(.9)-11

y=5.4-11

y=-5.6

I hope this is right, and that it helps!

Answer:

2 , -4 , (2,0)

Step-by-step explanation:

The slope of the linear function is 2.

The y-intercept of the linear function is -4.

The solutions of the linear function are (0, -4), (1, -2), (2, 0), etc..

The graph is given below.

The equation of a line is given by:

y = mx + c

where m is the slope of the line and c is the y-intercept.

Example:

The slope of the line y = 2x + 3 is 2.

The slope of a line that passes through (1, 2) and (2, 3) is 1.

We have,

The linear function is y = mx + c

The linear function passes through (-2, -8) and (1, -2)

Now,

m = (-2 + 8) / (1 + 2)

m = 6/3

m = 2

The slope of the linear function is 2.

Now,

(-2, -8) = (x, y)

-8 = 2 x (-2) + c

-8 = - 4 + c

c = -8 + 4

c = -4

The y-intercept is -4.

The equation of the linear function.

y = 2x - 4

The solution of the line are (0, -4), (1, -2), (2, 0), etc..

When x = 0,

y = -4

When x = 1,

y = -2

When x = 2,

y = 0

Now,

The graph of the line is given below.

Thus,

The slope is 2.

The y-intercept is -4.

The solutions are (0, -4), (1, -2), (2, 0), etc..

ur question is incomplete

Answer:

Because it will take a lot of time to do

Answer:

the answer for this one is B

Answer:

The answer would be B.

Step-by-step explanation:

Just substitute x for 5.

For example, A is 2+x=3.

Just put 5 instead of x.

It would be 2+5=3.

But that isn't the answer because 2+5 is 7, not 3.

For B, sub the x for 5 just like we did for A.

It would usually be 3x=15

But sub the x with 5.

It would turn into 3x5=15

And that is right, because if you multiple 5 three times, it would be 15.

I hope this helps, I did my best. Have a great day!

Answer:

other root: x = 9

p = 7

Step-by-step explanation:

first, find p:

(8)² - (3p - 4)8 + 11p -5 = 0

64 - (24p - 32) + 11p - 5 = 0 –––––> 64 - 24p + 32 + 11p - 5 = 0

91 - 13p = 0

-13p = -91

p = 7

plug in p to find the polynomial:

x² - (3(7) - 4)x + 11(7) - 5 = 0

x² - (21 - 4)x + 77 - 5 = 0

x² - 17x + 72

find the roots:

we know that 8 is one of the roots, so one factor is (x - 8)

the other number needs to be something that equals -17 when added with -8 and 72 when multiplied by -8

that number is -9

so the poly nomial factors to be: (x-8)(x-9)

so the roots are x = 8 and x = 9

Answer:

p = 7

Step-by-step explanation:

x²-(3p-4)x+11p-5=0    ...(1)    Root: 8, x-8 is factor

(x-8) (x- (11p-5)/8) = 0

x² -8x - ((11p-5)/8)*x + (11p-5) = 0

x² - (8 + (11p-5)/8) x + 11p-5 = 0   ----(2)

compare(1) and (2): 3p-4 = 8 + (11p-5)/8

24p - 32 = 64 + 11p - 5

13p = 91

p = 7

check: x²-(3p-4)x+11p-5 = x²- 17x + 72 = (x-8)(x-9)

Answer:

Step-by-step explanation:

Answer:

The length and breadth of the fence are 80 and 70 meters, respectively.

Step-by-step explanation:

Let suppose that fencing has a rectangular form. The length to breadth ratio is [tex]\frac{8}{7}[/tex]. Dimensionally speaking, the total cost for fencing the plot ([tex]C[/tex]), measured in monetary units, is the product of perimeter of the rectangle ([tex]p[/tex]), measured in meters, and unit cost ([tex]c[/tex]), measured in monetary units per meter, that is:

[tex]C = c\cdot p[/tex] (1)

[tex]C = 2\cdot c\cdot (w+l)[/tex] (2)

Where:

[tex]w[/tex] - Breadth of the fence, measured in meters.

[tex]l[/tex] - Length of the fence, measured in meters.

By applying the ratio described above, we reduce (2) into this form:

[tex]C = 2\cdot c\cdot \left(\frac{1}{r} +1\right)\cdot l[/tex] (3)

Where [tex]r[/tex] is the length to breadth ratio, no unit.

If we know that [tex]C = 60000[/tex], [tex]c = 200[/tex] and [tex]r = \frac{8}{7}[/tex], then the length and breadth of the rectangle are, respectively:

[tex]l = \frac{C}{2\cdot c\cdot \left(\frac{1}{r} +1\right)}[/tex]

[tex]l = \frac{60000}{2\cdot (200)\cdot \left(\frac{7}{8}+1 \right)}[/tex]

[tex]l = 80\,m[/tex]

[tex]w = \frac{l}{r}[/tex]

[tex]w = \frac{80\,m}{\frac{8}{7} }[/tex]

[tex]w = 70\,m[/tex]

The length and breadth of the fence are 80 and 70 meters, respectively.
