Step-by-step explanation:

Let the remaining angle be z.

45+z=90

z=90-45

z=45

y=9(isoceles triangle)

Then,

By pythagoras theorem,

x=9root2

answer: 12   they all have at least 28 days

step-by-step explanation: haha

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
