Which polynomial does this group of tiles represent

2 answers:

6 0

I believe A: 2x^2 + 3x + 1

This is because there are 2 tiles with x^2 on it, 3 tiles with x on it and 1 tile with a 1 on it.

Plz someone help I will mark brainlest diameter is 8.8 yd

sweet [91]

Answer:

60.79 square yards.

Step-by-step explanation:

d = 2r; d = 8.8.

8.8 = 2r

r = 8.8 / 2

r = 4.4 yards.

Since we now have the radius, we can find the area of the circle, which can be found using πr^2, or 3.14 * r^2.

4.4^2 * 3.14 = 19.36 * 3.14 = 60.7904.

Since the question tells us to round to the nearest hundredth, our final answer will be 60.79 square yards.

Hope this helps!

Which is equivalent to √3/√8 when denominator is "rationalized"?

TEA [102]

Step-by-step explanation:

$\dfrac{\sqrt3}{\sqrt8}=\dfrac{\sqrt3\cdot\sqrt2}{\sqrt8\cdot\sqrt2}=\dfrac{\sqrt{3\cdot2}}{\sqrt{8\cdot2}}=\dfrac{\sqrt6}{\sqrt{16}}=\dfrac{\sqrt6}{4}$

$\sqrt{ab}=\sqrt{a}\cdot\sqrt{b}\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{a}=b\iff b^2=a\ \text{for}\ a\geq0\ \wedge\ b\geq0\\\\\sqrt{16}=4\ \text{because}\ 4^2=16$
