What is the smallest integer to have three different prime factors?

Step-by-step explanation:

A prime number is a positive integer which have exactly 2 distinct factors, 1 and itself.

The first three prime numbers are 2, 3 and 5.

Hence the smallest integer to have three different prime factors = 2 * 3 * 5 = 30.

area of part 1:

a1=base*height/2=(8+2)*(8-2-2-1)/2=10*3/2=15 ft^2

area of part 2:

a2=length*width=(8+2)*1=10 ft2

area of part 3:

a3=length*width=8*2=16 ft2

total shaded area : a1+a2+a3=41 ft2

total area of the reactangle : a=16*8=128 ft2

total area of the nonshaded region : 128-41=87 ft2

she will most likely have 33
