Geometry math question no Guessing and Please show work thank you

hichkok12 [17]

we will use formula

$\theta=\frac{180(n-2)}{n}$

where

theta is angle

n is number of sides

we are given

n=15

we can plug it

$\theta=\frac{180(15-2)}{15}$

now, we can solve for theta

$\theta=\frac{60(15-2)}{5}$

$\theta=12*13$

$\theta=156$

so,

option-D.........Answer

First of all, we can observe that

$x^2-6x+9 = (x-3)^2$

So the expression becomes

$\dfrac{x^2-4}{\sqrt{(x-3)^2}} = \dfrac{x^2-4}{|x-3|}$

This means that the expression is defined for every $x\neq 3$

Now, since the denominator is always positive (when it exists), the fraction can only be positive if the denominator is also positive: we must ask

$x^2-4 \geq 0 \iff x\leq -2 \lor x\geq 2$

Since we can't accept 3 as an answer, the actual solution set is

$(-\infty,-2] \cup [2,3) \cup (3,\infty)$

Anyone please help me? tysm!

Answer:

6 ft

Step-by-step explanation:

The surface area of a cube is given by

SA = 6s^2

216 = 6s^2

Divide each side by 6

216/6 = 6s^2/6

36 = s^2

Take the square root of each side

sqrt(36) = sqrt(s^2)

6 =s

Each side is 6ft

for a two week period, john and amanda had the following transactions occur to their cheking account: a deposit of $1,644.50;che

QveST [7]

a deposit of $1,644.50;checks written for $190, $45, and $7.50; and debit card transactions for $30, $5.59, $7.20, and $21.30.

amount deposited = 1644.50

debit card transactions for $30, $5.59, $7.20, and $21.30.

We add all the debit card transactions

30 + 5.59 + 7.20 + 21.30 =64.09

checks written for $190, $45, and $7.50

Add all the check written amounts

190 + 45 + 7.50=242.5

To find ending balance , we subtract the debit card transactions and check written from the deposit amount

1644.50 - 64.09 - 242.5 = 1337.91

$1,337.91 is the ending balance for this time frame
