4-2 Writing Equations in Slope-Intercept Form
So, the correct choice is J.
The midpoints of the sides of the large square are joined to form a smaller square. What is the area
of the smaller square?
2
64 cm
2
128 cm
2
248 cm
2
256 cm
Let the length of a side of the smaller square be represented by c. So, the formula for area of the square would be A
2
= c
. Use the Pythagorean theorem to find the length of a side of the smaller square.
2
So, since A = c
, A = 128. The correct choice is B.
If
9?
x
Solve for x.
