Answer:
17.5
Step-by-step explanation:
(7)*(5)*(.5)= 17.5
A square's diagonal has a length equal to √(2) times the length of its sides. So if the side length is <em>x</em>, then the diagonal is such that
√(2) <em>x</em> = 10 cm
→ <em>x</em> = 10/√(2) cm ≈ 7.07 cm
The perimeter of a square is 4 times its side length, so the perimeter is
4 (10/√(2) cm) = 40/√(2) cm ≈ 28.3 cm
which makes 28.4 cm the closest answer.
2.3 + w > 18
-2.3 -2.3
w > 15.7
Use the formula:
y2-y1
———
x2-x1
So for this problem it would be:
6-5
——
7-4
= 1
—
3
Hope this helped, if it did I would appreciate it if you would consider giving me brainliest!
