Answer:

The perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

Step-by-step explanation:

According to the diagram, we get the following facts:

i) For one triangle (x=1), the total perimeter is (y=2\cdot 3 + 1\cdot 4 = 10).

ii) For two triangles (x = 2), the total perimeter is (y = 2\cdot 3 +2\cdot 4 = 14)

iii) For three triangles (x = 3), the total perimeter is (y = 2\cdot 3 +3\cdot 4 = 18)

iv) For four triangles (x = 4), the total perimeter is (y = 2\cdot 3 +4\cdot 4 = 22)

From these information we conclude that the equation that determines the perimeter of the figure as a function of the number of triangles is y = 6 + 4\cdot x.

List the measurement below from smallest to largest .7 cm 18 mm 1 m 3 dm
Ivanshal [37]
In order to list the measurements from smallest to largest, we convert all the measurement to a common unit. In this item, we convert the given to meters, m.

A. The conversion factor to be used here is 1 m = 100 cm
      (7 cm)(1 m / 100 cm) = 0.07 m

B. Conversion factor: 1 m = 1000 mm
     (18 mm) (1 m / 1000 mm) = 0.018 m

C. Let us list this as is, 1 m

D. The conversion factor here is 1 m = 10 dm
    (3 dm)(1 m / 10 dm) = 0.3 m

By the converted values, we are then able to arrange the given measurements.Hence, the arrangement should be 18 mm, 7 cm, 3 dm, and 1 m.

1) (1 Point) : If-18 - x=9, then -5 +6x = ?
TiliK225 [7]
-167, because if you solve -18-x=9, x will be equal to -27. When you put -27 in place of the x in -5+6x, you get -167. Have a nice day!
