Answer:
x= 2,4,6,8.......any even number
Step-by-step explanation:
Perimeter is 4+4 + 3x+3x = 8+6x
The result of 8 + 6 times a number should be a multiple of 4.
PERIMETER AREA
8+(6*2)= 8+ 12 = 4*5=20
8+(6*4) = 8 +24=32 4*8=32
8+(6*6) =8+36 =44 4*11=44
8+(6*8)=8+48=56 4*14=56
And so on.......
Answer: the arc elasticity percentage change from 80 to 100 is 22%
Step-by-step explanation:
formula for arc-elasticity percentage change is given as;
{ [Xₙ - X₀] / [ (X₀+Xₙ) / 2] } × 100
X₀ is old value, Xₙis new value
Now from our question
old value X₀ = 80
new value Xₙ = 100
WE SUBSTITUTE
Arc-Elasticity = { [100 - 80] / [ (80+100) / 2] } × 100
Arc-Elasticity = { [20] / [ 180 / 2] } × 100
Arc-Elasticity = (20/90) × 100
Arc-Elasticity = 22.22 ≈ 22%
Therefore the arc elasticity percentage change from 80 to 100 is 22%
