2. The sum of 3 consecutive integers is 66.
a) Write a variable equation for the given information.
Assign variables:
Let, x = the 1st integer
x + 1 = the 2nd integer
x + 2 = the 3rd integer
x + x x = 66
Simplify
3x = 66
b) Find the integers.
The first integer is x
3x = 66

The perimeter(P = 2l + 2w) of a rectangle is 24 cm.
The length is twice the width. Find the area (A = lw).
Assign variables:
Let, l = 2w
w = w
P = 24
Substitute into the perimeter formula.
Simplify
24 = 2(2w) + 2(w)
Find the area (A = lw).
24 = 4w + 2w
A = (8)(4)
Multiply
24 = 6w
Divide
A = 32 6 6
4 = w
Area = 32 cm2
8 = l
Find the length. The length is twice the width.
