Can someone please help me on this problem? I don’t understand it...

andrezito [222]

Answer:

A = -9, B = 65

Step-by-step explanation:

Take the square root of both sides of the equation:

h + 9 = ±√65

Subtract 9 from both sides of the equation:

h = -9 ± √65

Comparing this to the form

h = A ± √B

we see that A = -9 and B = 65.

_____

A lot of math is about matching patterns of numbers and variables. Here, you're asked to match the expression -9±√65 to the pattern A±√B and identify the values for A and B that make these expressions identical.

It should not be difficult to see that the stuff on the left side of ± is the value of A. That stuff is -9.

The stuff under the radical is the value of B. That stuff is 65.

find the area of a regular hexagon with an apothem 10.4 yards long and a side 12 yards long. round your answer to the nearest te

irakobra [83]

The answer is 374.4 yards.

There are 2 ways to calculate the area of a <span>a regular hexagon.
It is given:
apothem: b = 10.4 yards
side: a = 12 yards

1. The direct way is to use the formula for the regular hexagon without using an apothem:
</span> $A= \frac{3 \sqrt{3} }{2} a^{2}$
<span>where
A - the area of the </span><span>hexagon
a - the side of the </span><span>hexagon

Therefore:
</span><span> $A= \frac{3 \sqrt{3} }{2} 12^{2}$
</span><span> $A= \frac{3 \sqrt{3} }{2} 144$
</span><span> $A= 374.4$
</span>
2. The indirect way is to sketch the hexagon with 3 diagonals and create 6 triangles. Then, it is necessary to calculate the area of one triangle and multiply it by 6. In this triangle, apothem is actually the height.
The area of the hexagon is:
A = 6 · A₁
where:
A - the area of the <span>hexagon,
</span>A₁ - the area of the triangle

$A_{1}= \frac{a*h}{2}$

where
h - <span>height of the triangle.
</span>

Since apothem (b) of the hexagon is the height (h) of the triangle, then:
$A_{1}= \frac{a*h}{2}$
<span> $A_{1}= \frac{12*10.4}{2}$
</span><span> $A_{1}= 62.4$
</span>
Thus, the area of one triangle is 62.4 yards.

To calculate the area of the hexagon, we will multiply it by 6:
<span>A = 6 · A₁
</span><span>A = 6 · 62.4
</span>A = 374.4 yards

<span>In both cases, the result is 374.4 yards.</span>The answer is
