Answer:

The length of the fence needed to surround this garden is 188\ m

Step-by-step explanation:

Let

x----> the length of the rectangular fence

y----> the width of the rectangular fence

we know that the area of the rectangular fence is equal to

A=xy

A=2,184\ m^{2}

so

2,184=xy -----> equation A

we have

x=10+y -----> equation B

Substitute equation B in equation A

2,184=(10+y)y

y^{2}+10y-2,184=0

using a graphing tool

solve the quadratic equation

The solution is y=42\ m

see the attached figure

Find the value of x

x=10+y ----> x=10+42=52\ m

Find the perimeter of the rectangular fence

The perimeter is equal to

P=2(x+y)

substitute the values

P=2(52+42)=188\ m

Is (-2, 0) the solution to the system below?
o-na [289]

Answer:

No, the answer is (-3/7, -33/7)

Step-by-step explanation:

y=-3x-6 can be rewritten as y+3x=-6

so, our two equations are:

1. y+3x=-6

2. 3y+2x=-15

we can multiply the first equation by 3.

1-1.3y+9x=-18

Now we can subtract the second equation from equation 1-1.

3y+9x=-18

<u>-(3y+2x=-15)</u>

7x=-3

x=-3/7

Now that we have x, let's plug it into an equation. I will plug it into the first equation.

y=-3(-3/7) - 6

y=9/7 - 6

y=-33/7

so the points are (-3/7, -33/7)

In the figure, AB ll CD and<br>m4=85<br>What is m5​
AveGali [126]

Answer:

85°

Step-by-step explanation:

m∠4  measures 85 degrees.

m∠4 and m∠5 are alternate interior angles.

The alternate interior angles theorem states that <u>all pairs of alternate interior angles are congruen</u>t, or equal.

m∠4 ≅ m∠5

So, m∠5 should also be 85° as well as m∠4.

If s=7 cm and t= 24 cm, what is the length of r?
marin [14]
A^2 + B^2 = C^2.

so 49 + 576 = C^2

625 = C^2

Now find the square root of 625.

25 = C (in your case r)
