The P is 16x^2 -12 and Perimeter is the distance around the edge of a shape. So you divide your equation by 4 and the answer you get is 4x^2 - 3

William is taking the 25-question, multiple choice American Mathematics Competition. Each question has five answer choices. Will

o-na [289]

Given that William guesses random answers for the last four questions and that each question has five answer choices.

The probability that he gets an answer correct is 1 / 5.

The probability that he did not get an answer correct is 4 / 5.

The probability that he will not get any of the 4 questions correctly is

$\left( \frac{4}{5} \right)^4= \frac{256}{625}$

Therefore, the probability that he gets at least one of the 4 questions correctly is

$1-\frac{256}{625}= \frac{369}{625} =0.59=59\%$

√48a^4 b^5 c^3 d simplify and keep it in radical form

Morgarella [4.7K]

I will assume the square root extends all the way across.

$\sqrt{48a^4b^5c^3}$

$\sqrt{2^4\cdot3\cdot a^4b^5c^3}$

$\sqrt{(2^2)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c}$

$\sqrt{(4)^2\cdot3\cdot(a^2)^2\cdot(b^2)^2\cdot b\cdot c^2\cdot c}$

$\sqrt{(4\cdot a^2 \cdot b^2 \cdot c)^2\cdot3\cdot b\cdot c}$

$4\cdot a^2\cdot b^2\cdot c\sqrt{3\cdot b\cdot c}$

$\boxed{4a^2b^2c\sqrt{3bc}}$
