let length of the rectangle be l

length is 6 cm longer than the width, w

l = w + 6

 perimeter of rectangle is 72 cm

= 2l + 2w

substitute l = w + 6

2(w+6) + 2w = 72

4w + 12 = 72

4w = 60

x = 15

ans is C. 15 cm

Answer:

Step-by-step explanation:

Perimeter = 2 x (length + width)

72 = 2 x ( l + w)

Because l = w +6

72 = 2 x (w + 6 + w)

= 2 x (2w + 6)

= 4w + 12

4w = 60

w = 15 cm

The answer is C.

Graph the system of equations.
Y_Kistochka [10]

Answer:

Step-by-step explanation:

I cannot use the line tool for you, but I can rewrite the equations

y = -x + 4 is good enough

Two points for this graph:

x = 0 -> y = 4 gives the point (0, 4)

x = 1 -> y = 3 gives the point (1, 3)

18x + 6y = -6

6y = -18x - 6

y = -3x - 2

Two ponts for this graph:

x = 0 -> y = -2 gives the point (0, -2)

x = 1 -> y = -5 gives the point (1, -5 )

. XYZ has vertices X (–5, 2), Y (0, –4), and Z (3, 3). What are the vertices of the image of X’Y’Z’ under the translation (x, y)
Katen [24]

Answer:

X' = (2, -3)

Y' = (7, -9)

Z' = (10, -2)

Step-by-step explanation:

to find the translation of each point substitute the x and y with the the numbers

eg; X ( -5,2) the x is 5 and the y is 2

so -5 + 7 = 2 (the x value)

2 - 5 = -3 ( the y value)
