Answer:
John added 1 +4 +4 to get 9 (12x12 = 144)
Step-by-step explanation:
12x12 actually equals 144
1 + 4 +4 = 9 so it appears John just added all the digits of 144 to get 9
(3x)^3+3(3x)^2*-1 +3(3x)(-1)^2+(-1)^3 then simply that down to 27x^3-27x^3+9x-1
The linear relationship should be

Answer:
Each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
Step-by-step explanation:
Make a sketch and find an isosceles triangle formed by the diagonal, shorter base and the lateral side of the trapezoid.
Thus you have the lateral sides of the trapezoid congruent to the shorter base.
Your trapezoid then has the sides of 5:3:3:3 units.
In total, there are 5 + 3 + 3 + 3 = 14 units.
Hence, each unit is of 28/14 = 2 inches long and the sides are of 6 in, 6 in, 6 in and 10 in.
Would you mind giving me brainliest?
