Akite has side lengths of 2 feet and 4 feet. each side length is increased by the same number of feet. the expression represents the perimeter of the larger kite:

(x + 2) + (x + 2) + (x + 4) + (x + 4)

which expression is equivalent to the expression for the perimeter of the larger kite?

The x terms add up to 4x and the numbers add up to 12 .

4x + 12 = 4(x + 3)

hello,

b) 62.47% of the students are between 14 and 18 years old.

step-by-step explanation:

mean = 15 and standard deviation = 2

student between 14 to 18

formula used z-score

for age 14 , z score

using z-table , p(z> -0.5)=0.3085

for age 18 , z score

using z-table , p(z< 1.5)=0.9332

p(-0.5< z< 1.5)=0.9332-0.3085 = 0.6247

thus, 62.47% of the students are between 14 and 18 years old.
