I think D and E. The point slope formula is y-y₁=m(x-x₁).
Rational, because they follow a pattern and end. They make sense.
Answer:
Use this formula: length + length + width + width = perimeter
Step-by-step explanation:
4(4x^2+4x +1)
4(2x+1)(2x+1)
the answer to the question
Answer:
Tan(∠A) is 4/3.
Step-by-step explanation:
To answer this question, we first need a basic understanding of sin, cos, and tan. The sin of an angle is the opposite over hypotenuse, the cos is adjacent over hypotenuse, and the tan is the opposite over adjancent.
Since sin(∠A) is 4/7, that makes 4 the opposite and 7 the hypotenuse.
Since cos(∠A) is 3/7, that makes 3 the adjacent the 7 the hypotenuse again.
So to get tan(∠A), we just have to put 4/3 since that is the opposite over the adjacent.
