The expression V − E + F is an illustration of the Euler's formula.

The expression V − E + F is always 2

<h3>How to determine the true statement?</h3>

The equation is given as:

V - E + F = 2

Where:

  • V represents the vertices
  • E represents the edges
  • F represents the faces

According to the Euler's formula, the relationship between V, E and F is:

V + F = 2 + E

Subtract E from both sides

V - E + F = 2

Hence, the expression V − E + F is always 2

Solve the expressions on the left when x=5<br>3x-10<br>x^2-15<br>5x-21<br>x+10-8​
Nitella [24]

Answer:

5

10

4

7

Step-by-step explanation:

Apply the value of x into the expressions:

3(5) - 10 = 15 - 10

           = 5

5² - 15 = 25 - 15

          = 10

5(5) - 21 = 25 - 21

             = 4

5 + 10 - 8 = 15 - 8

               = 7
