22.4/4 = 5.6 cm

5.6^2 = 31.36 cm^2 per side

Since the later surface area only counts for 4/6 sides on the cube, (31.36)(4) = 125.44 cm^2

The given two polygons are similar to one another ~

Sides of the given polygons are in ratio of :

\qquad \sf  \dashrightarrow \: 28 : 4

to put in simple Ratio ~

\qquad \sf  \dashrightarrow \: 7: 1

So, the sides of the larger polygon are :

  • 4 × 7 = 28

  • 6 × 7 = 42

  • 3 × 7 = 21

  • 4 × 7 = 28

  • 7 × 7 = 49

  • 3 × 7 = 21

  • 3 × 7 = 21

  • 4 × 7 = 28

Now, to find the Perimeter of larger polygon ~ add the side length of all sides :

\qquad \sf  \dashrightarrow \:p = 28 + 42 + 21 + 28 + 49 + 21 + 21 + 28

\qquad \sf  \dashrightarrow \:238 \:  \: units

Scilla [17]

Answer:

B. $3336.67

Bi weekly means every 2 weeks

There are 52 weeks in a year,  so there are 52/2 = 26  26 pay periods for bi-weekly

1540*26 =40040 is the yearly salary

There are 12 months in a year

Divide the yearly salary by 12

40040/12 = 3336.67

What value of x will make this equation true 2x-6=3x+1-x-7
Semmy [17]

2x-6=3x+1-x-7

Simplify the right side by combining like terms:

2X - 6 = 2X - 6

Because both sides of the equation are the same any value of X will make this true.
