X^2+9x+9x+81
x^2+18x+81
for factoring it
The answer is 12.58 rounded up it would be 13 so the correct answer is A
The answer is y=3x-6. (B). First you subtract 6x from both sides. Then you get -2y=12-6x. Now, you divide both sides by -2. This gets you the final answer; y=3x-6 or y=-6+3x.
6,004,720,080 in expanded form is (6x1,000,000,000)+(4x1,000,000)+(7x100,000)+(2x10,000)+(8x10)
actually box 3 is correct.
because their radiuses are easy to find
but the tangent line is x=-4 or x=4
