It would kind of help if there was a graph that we could choose to help you
Answer:
18
Step-by-step explanation:
CALCULATER
The input is the y
y = x^2 - 5
plug in what we're given
-1 = x^2 -5
add 5 to both sides
4 = x^2
take the square root of both sides
2 = x
Hope this helps :)
Answer:
128 km²
Step-by-step explanation:
a²+b²=c²
So, one of the sides equals 128 square rooted, because 8²=64, and 64 times 2 equals 128. The area of a square is side times side, so it's side². So, instead of simplifying the square root of 128, get rid of the square root. The answer is 128 km²
