Formula for perimeter of a rectangle: P = 2W + 2L
Here, P = 2(x-3 ) cm + 2(3x+7) cm = 2x - 6 + 6x + 14 (cm)
Combine like terms: 8x + 8 cm (simplest form) This is the perimeter.
Now let x = 4: P(x=4) = 8(4) + 8 cm = 40 cm
Answer:
36 people
Step-by-step explanation:
If the yearbook club had 1/2 the participants attend the meeting, than all of them would be represented by 18 x 2, or 36 (since two halves make a whole)
The 8oz because double that is 16oz and the price doubled is 2.72
Paralel lines have same slope
if green line is paralell to red line
and the slope of the green line is 1/4
slope of red line is 1/4 also
All work is shown in picture below.
