Answer:
50
Step-by-step explanation:
To do this we know that a^2+b^2 = x^2
for b:
The distance between -1 and 4 is 5. we will use 5^2
for a:
The distance between -3 and 2 is also 5. we we use 5^2
put into the formula
5^2+5^2=c^2
25+25=c^2
50=c^2
so the square root of 50 is the distance between the points
