Find the lengths of a and b.
a: a=10 ft, b=10 ft
b: a= 5 square root 2 ft, b= 10 ft
c: a= 20 ft , b= 20 ft
d: a= 5 square root 2 ft , b= 5 square root 2 ft

i think that you should ask google for the answer to that problem because if we don't know it google does

the answer is 150.6

step-by-step explanation:

substitution for (0,1)

y=x^2+4x+1

1=0^2+4(x)0+1

1=0+4(x)0+1

1=4(x)0+1

1=0+1

1=1

substitution for (-3,-2)

y=x+1

-2=-3+1

-2=-2

804.75
