Answer:
<em> = n² + 4n ; n = 11 </em>
Step-by-step explanation:
= 
[2 
+ (n - 1)d]
~~~~~~~~~
= 5
d = 7 - 5 = 2
= [ 2(5) + 2(n - 1)] = ( 8 + 2n ) = 4n + n²
<em> = n² + 4n</em>
n² + 4n = 165
n² + 4n - 165 = 0
(n + 15)(n - 11) = 0 ( n ≥ 0 ) ⇒ <em>n = 11</em>
<h3>The surface area of cube is 162.24 square inches</h3>
<em><u>Solution:</u></em>
<em><u>The surface area of cube is given as:</u></em>
Where,
"s" is the length of each side of cube
From given,
s = 5.2 inches
Therefore,
Thus the surface area of cube is 162.24 square inches
Answer:

Y2-Y1 / X2 - X1
Answer:
2 < x < 5
Step-by-step explanation:
<u>< This symbol means 'less than'</u>. The number you put on its left side is less than the number on its right side.
<u>> This symbol means 'greater than'</u>. The number put on its left is greater than its number on the right.
Think of them like a mouth. Remember the 'open side' wants to eat more.
Translate words to symbols:
'x is less than 5'
x < 5
'x is greater than 2'
x > 2
Put them together. The < and > symbols change directions, but x on the closed side of 5. Keep x on the open side of 2.
2 < x < 5
Don't confuse < and > with ≤ and ≥.
≤ and ≥ mean 'less than OR equal to' and greater than OR equation to'.
20 dimes; 0 quarters= $2.00; 20 dimes; 1 quarter= $2.25 and so on
