Solve for l.
p = 2l + 2w
l = 2/(p - w)
l = 2(w - 2p)
l = (p - 2w)/22

The answer to your question is: L = (P - 2W) / 2

Step-by-step explanation:

                      Equation              P = 2L + 2W            solve for L

                                                  2L + 2W = P          

                                                  2L = P - 2W              pass 2W to the right side

                                                                                    subtracting

                                                  L = (P - 2W) / 2        pass 2 to the right side

                                                                                   dividing

the answer is b. 60. each interior angle in 120, so the exterior angle must be 60 in order to add up to 180

step-by-step explanation:

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.
