A designer places 4 identical squares on a surface and spaces them 3 5/16 inches apart. Each square is 7 1/4 inches wide. If you lay 12 squares horizontally in a row, what is the total distance across the squares?

Number of spaces would be number of squares - 1

You would have 12 squares and 11 spaces.

Multiply number of each by their size then add the two together:

12 x 7 1/4 = 87 inches

11 x 3 5/16 = 36 7/16 inches

Total = 87 + 36 7/16 = 123 7/16 inches

123 7/16 inches

3: 2

step-by-step explanation:

shorter piece is 2: 3, so just reverse it, and you get 3: 2

step-by-step explanation:

f(x)=2x^2 -1 

translation is a function transformation that transform the function in a way of translating. by translating the function its graph is moved  up an down. moving the function f(x) 2 units to the left will be the new function g(x) with the equation: g(x)=f(x+2)=2(x+2)^2 -1
