Step-by-step explanation:
You can use cubes to help you write an expression and model the problem by using the cubes in replace of numbers. It should be a lot easier. Then after you finish you just have to write it down. There are other ways, but this is just one.
With Elimination system:
Substract -4x + y = -1 with -2x + y = 1
and... the result: 2x = 2, so x = 1
Subtitution: -2x + y = 1
⇔-2 . 1 + y =1
⇔ -2 + y = 1
⇔y = 3
The final answer is D ( 1, 3)
The diagonal's length is about 3.5 inches; to solve, use the Pythagorean theorem (a^2 + b^2 = c^) to determine the length of the diagonal using one of the two triangles it forms by cutting the square in half. One triangle has three sides: 6 in, 6 in, and the unknown diagonal.
6^2 + 6^2 = c^2 Plug in the known sides
36 + 36 = c^2 Simplify
72 = c^2 Simplify
~3.5 = c Take the square root of both sides
