Answer:

EF =  62

Step-by-step explanation:

Given

CG = 11x-5

GD=13x-15

EF=12x+2

Required

Determine EF

Since EF is a bisector of CD at G, then

CG = GD

11x- 5 = 13x - 15

Collect Like Terms

11x - 13x = 5 - 15

-2x = -10

Solve for x

x = -10/-2

x = 5

Substitute 5 for x in EF=12x+2

EF = 12 * 5 + 2

EF =  60+ 2

EF =  62

E-4 - 5 - 6 - → The perimeter of a rectangle is 425 yards. The length and width of the rectangle are each multiplied by 6. What
Alex73 [517]

Answer:

2550yards

Step-by-step explanation:

Perimeter of a rectangle = 2L + 2W

L is the length

W is the width

If perimeter of a rectangle is 425 yards, then;

425 = 2L + 2W

425 = 2(L+W)

L+W = 425/2 .... 1

If the length and width of the rectangle are each multiplied by 6

P = 6(2L) + 2(2W)

P = 12L + 12W

P = 12(L+W) .... 2

Substitute 1 into 2

P = 12(425/2)

P = 6*425

P = 2550yd

Hence the perimeter of new triangle is 2550yards
