I’d love to help I pretty sure it is C-6
Answer:
D) -50
Step-by-step explanation:
The answer is D.
Numbers below zero would be negative. This eliminates B and A, as they are positive.
Numbers above zero are positive.
<em>The answer is not C because that would be 25 degrees below zero</em>, not 50 below.
That leaves us with D. D is -50, which is also stated as "50 below zero".
So, our best answer would be D.
Answer:
120.
Step-by-step explanation:
Using the Pythagoras theorem:
(30√2)^2 = x^2 + x^2 where x =length of each side of the square
1800 = 2x^2
x^2 = 900
x = 30.
So the perimeter = 4*30 = 120.
