Answer:

DF = 38

GE = 40

Step-by-step explanation:

Given

DH = 2y + 6,

HF = 4x + 1,

HE = 3x + 2

GH = 20.

See attachment for parallelogram.

Required

Find GE and DF

From the attachment:

GH= HE

Substitute values for GH and HE

20 = 3x + 2

Subtract 2 from both sides

20-2 = 3x + 2-2

20-2 = 3x

18= 3x

3x = 18

Divide both sides by 3

x = \frac{18}{3}

x=6

GE = GH + HE

GH= HE

So:

GE = GH + GH

GE = 20 + 20

GE = 40

To find DF, we find y first:

DH = HF

2y + 6 = 4x + 1

Subtract 6 from both sides

2y +6- 6 = 4x + 1-6

2y = 4x + 1-6

Substitute 6 for x

2y = 4*6 + 1-6

2y = 19

Divide both sides by 2

y = \frac{19}{2}

y = 9.5

DF is then calculated as"

DF = DH + HF

DF = 2y+6 + 4x+1

Substitute values for x and y

DF = 2*9.5+6 + 4*3+1

DF = 38

Write an equation of a line that has a y-intercept at (0, -6)
galben [10]

Answer:

y=x-6

Step-by-step explanation:

    First to write this equation you will need to know <em>slope intercept form</em> which is the equation that the people that wrote this problem are presumably looking for. Slope intercept form can be simply written as y=mx+b . The variable m would be the slope while the variable b would be the y -intercept.

    So to find out this we would have to assume that m or the slope would have to be 1 so we would have y=1x+b or y=x+b.  

    Now we have the first half of the equation we can move on to the variable b or the y-intercept (0,-6) . To find the variable b we will just have to graph the point (0,-6) which as you can see from the picture is the y-intercept and that is -6 units below 0. So the final answer will be y=x-6

son4ous [18]

Answer:

Circle requires ≈ 20 m of edging

Step-by-step explanation:

A = πR²

R = √(A/π)

C = 2πR = 2π√(A/π)

C = 2π√(30/π) = 19.41625... ≈ 20 m

square needs ≈ 22 m of edging

equilateral triangle needs ≈ 25 m of edging
