The mean is the average...to find the mean, add up all the numbers, then divide by how many numbers there are.
Example :
ur set of numbers : 1,2,3,4
add up all the numbers and divide by how many there are :
(1 + 2 + 3 + 4) / 4 = 10/4 = 2.5...so 2.5 is ur mean (average)

Step-by-step explanation:Hope it helped
Answer:
Length = Width * 3
Width = 2 ft
Length = 2 ft * 3 = 6 ft
Perimeter = (L * 2) + (W * 2)
P = 16 ft
Area = L * W = 12 square feet
Answer:
Step-by-step explanation:
12a)To rationalize the denominator, multiply the denominator and numerator by √5.
b) (a+b)² = a² + 2ab + b²
(1 +√3)² = 1² + 2*1*√3 + (√3)²
= 1 + 2√3 + 3
= 4 + 2√3
a = 4 ; b =2
13) (a + b)(a - b) = a² - b²
