<h3>By Euler's Formula </h3>

F + V = E + 2

<h2><u>Solution</u></h2>

F = 9

V = 14

E = ?

<h3>Substuting the values</h3>

⇨ 9 + 14 = E + 2

⇨ 23 = E + 2

⇨ 23 - 2 = E

⇨ 21 = E

Hence , the number of edges in polyhedron is 21.

-7- 2x² - 6 = −2x² + 1<br> First Step:<br> 13- 2x² = 2x² + 1<br> What property is this

lorasvet [3.4K]

Answer:

Combine like terms, although the provided answer is missing a "-" sign in front of the "13."

Step-by-step explanation:

Combine like terms. The -7 and -6 can be added to produce -13.

The correct result is <u>-</u>13 - 2x^2 = <u>-</u>2x^2 + 1 [Not _13- 2x² = _2x² + 1

Perhpas the initial equation is written incorrectly(?)

blagie [28]

Step-by-step explanation:

6x + 2 = 10x + 15

-13 = 4x

x = -13/4

If this is not the answer:

-13/4 = -3,25

boyakko [2]

Answer:

$\large\boxed{x=-8\ and\ y=9\to(-8,\ 9)}$

Step-by-step explanation:

$a)\ \text{Elimination method:}\\\\\left\{\begin{array}{ccc}3x+4y=12\\x+2y=10&\text{multiply both sides by (-2)}\end{array}\right\\\\\underline{+\left\{\begin{array}{ccc}3x+4y=12\\-2x-4y=-20\end{array}\right}\qquad\text{add both sides of the equations}\\.\qquad \boxed{x=-8}\\\\\text{Put the value of x to the second equation:}\\-8+2y=10\qquad\text{add 8 to both sides}\\2y=18\qquad\text{divide both sides by 2}\\\boxed{y=9}$

$b)\ \text{Substitution method:}\\\\\left\{\begin{array}{ccc}3x+4y=12\\x+2y=10&\text{subtract 2y from both sides}\end{array}\right\\\\\left\{\begin{array}{ccc}3x+4y=12&(1)\\x=10-2y&(2)\end{array}\right\qquad\text{subtract (2) to (1)}\\\\3(10-2y)+4y=12\qquad\text{use distributive property}\\(3)(10)+(3)(-2y)+4y=12\\30-6y+4y=12\qquad\text{subtract 30 from both sides}\\-2y=-18\qquad\text{divide both sides by (-2)}\\\boxed{y=9}\\\\\text{Put the value of y to (2):}\\x=10-2(9)\\x=10-18\\\boxed{x=-8}$
