Answer:
to find the distance between two points, in order to find the length of the triangle we need first to find the instance between the two points
distance between (2,9) and (2,4) .....a =5
distance between (2,4) and (6,4) .....b = 4
when we find the length of the side of the triangle , then we can apply the Pythagorean theorem to find hyp. c
a²+b²=c²

Answer:
8 7/24
Step-by-step explanation:
These are mixed fractions first you need to convert them
4 5/8= 37/8
3 2/3= 11/3
Take LCM of 3 and 8 which 24.
Multiply 37/8 with 3= 111/24
Multiply 11/3 with 8= 88/24
Now add both fractions
111/24 +88/24 =199/24
This is an improper fraction. Divide 199 by 24 to change this into mixed fraction
8 7/24
Step-by-step explanation:
x⁴+3x³-4x²=0
x²(x²+3x-4)=0
x²+3x-4=0
x²+4x-x-4=0
x(x+4)-1(x+4)=0
(x+4)(x-1)=0
x=-4 or 1
x can't be negative
therefore x=1
x+4=1+4=5
