Write an equation with integer solutions of:

x = ±6, y = 0
and
x = 0, y = ±12

a)x2 + y2 + 6 = 0
b)4x2 + y2 + 144 = 0
c)x2 + y2 − 6 = 0
d)4x2 + y2 − 1

 Option 'D' is correct.

Step-by-step explanation:

Since we have given that

x = ±6, y = 0

and x = 0 and y = ±12

And we need an equation which has above as an integer solutions.

So, it becomes,

Consider

Put x = 0, we get

Similarly,

Put y = 0,

Hence, Option 'D' is correct.

answer:   28.56 feet (approx)

step-by-step explanation:

since, triangle abc has measure of angle c equal to 55 degrees, measure of angle abc equal to 90 degrees, and length of bc equal to 20 feet.

we have to find out the measurement of segment ab.

therefore, tan 55° =

but bc = 20 feet.

⇒ tan 55 ° =  

⇒ ab = 20 × tan 55 °

⇒ ab = 20 × 1.42814800674

⇒ ab = 28.5629601348   ≈ 28.56 feet

a is 8.b is 10.c is 10.5. d is -.5

step-by-step explanation:

just minus the smallest number from the biggest.
