[5 points] Watch the instructional video Factoring Trinomials - With Algebra Tiles and then examine the algebra tile rectangle at right.
Write an equation showing that the area is equal to the product
of its side length factors (e. g. 8x2 - 10x - 3 = (2x - 3)(4x + 1)).
(Hint: Factor the trinomial by finding the lengths of the sides of the
rectangle.)

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.
