B. 

When you simplify the equation with the 180 surface area, you get the sqrt(30). This does not simplify any further. 

When you simplify the equation with the surface area of 120, you get sqrt(20), which simplifies further to 2sqrt(5). 

Then just subtract the second from the first.

Micah places a mirror on the ground 24 feet from the base of a tree. He walks
irina [24]

The height of tree is 8 feet

<h3><u>Solution:</u></h3>

Given, Micah places a mirror on the ground 24 feet from the base of a tree

At that point, Micah's eyes are 6 feet above the ground  

And he is 9 feet from the image in the mirror.  

To find : height of tree = ?

Let "n" be the height of tree

From the question, we can see there is a directly proportional relationship between heights and distances.

Proportional relationships are relationships between two variables where their ratios are equivalent.

\frac{\text { height of micah eyes above ground }}{\text { distance of micah from mirror }}=\frac{\text { height of tree above the ground }}{\text { distance of tree from mirror }}

\begin{array}{l}{\frac{6 \text { feet }}{9 \text { feet }}=\frac{n \text { feet }}{24 \text { feet }}} \\\\ {\frac{6}{9}=\frac{n}{24}} \\\\ {\text { n }=\frac{1}{3} \times 24} \\\\ {\text { n }=8}\end{array}

Hence, the height of the tree is 8 feet

Two inches are cut off one side of a square board and three inches are added to an adjacent side. The resulting rectangle has a
devlian [24]

Answer: 53

Step-by-step explanation:

The original square had a dimension of x and x was reduced by 2 which means x-2 and 3 was added so the formula will be x-2+3=54 and to work that out you have to do it backwards.

54-3=51

51+2=53

So the original dimension was 53inches
