A=4×-3 I think this is the equation
I'm pretty sure its B but I would double check before you put the answer in :)
We use the pithagorean formula: x^2 = 130^2 - 50^2 = 16900 -2500 = 14400;
then, x =

= 120 feet has the other dimension of the lot.
I think 1 is -540 and 2 is -290
Answer: 49
Step-by-step explanation:
The missing constant term in the perfect square is 49.
x^2 + 14x + 49
We need a squart root of something to make the factor add up equal to 14x. If it's a perfect square, we could divide 14 by 2, 14/2 = 7, and we multiply 7^2, we get 49, which is a perfect square.
