12.5 feet

step-by-step explanation:

∡ eia and ∡ kij are congruent

step-by-step explanation:

c.

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

the answer is 18 units because there are 18 small cubes inside the rectangle

hope this and p.s i am also in k12
